A catalyst and a method for manufacturing catalyst for polymerization ofunsaturated monomers and their mixes

The present invention relates to a process for the preparation of a catalyst for the polymerization of unsaturated monomers and mixtures thereof, such as olefins, bisphins and a (ethylenically unsaturated monomephs).

The use of soluble Ziegler-Natta type catalysts in olefin polymerization is of course well known in the art. in general, these soluble systems contain a Group IV-B metal compound and an alkyl-alcohol compound as cocatalyst, especially a alkylglycol compound. One of the sub-types of these catalysts is the sub-type containing the bis / cyclopentadiene compound of the group IV-B, especially titanium, in combination with alkali-based cocatalyst. Although there is still some speculation as to the actual structure of the active part of the catalyst in this subgenus of the Ziegler-Natta type for olefin polymerization, it is generally accepted that the active part of the catalyst is a cation or a degradation product thereof which causes alkylation of the olefin in the presence of a labile stabilizing anion.

The first advocates of this theory were Breslow i, and Long and Breslow, as shown in their respective articles, as shown in J. Am. Chem. Soc., 1959, Vol. 81, pp. 81-86 and in J.Am. Chem. Soc., 1960, Vol. 82, pp. 1953-1967. As indicated in these articles, various studies have suggested that the active part of the catalyst is an alkylolthiol complex or derivatives thereof when a titanium compound, e.g. bis (cyclopeitadieillo / titanium divalogen, for example, and an alkyloginate compound) is used as a catalyst or catalyst precursor. The presence of ions that are in equilibrium when using a titanium compound has also been suggested by Dacłhooskii, ^^ sokombo., Soyed., 1965, Vol. 7, pp. 114-115 and ^^ οΙ-Λογβ ^, Shilova and ShJLlov, J. Polym. Sci .., Part C, 1967, pp. 2333-2339. It's that when you use a titanium compound a part

159 196, the active catalyst is a complex cation, further suggested by Eisch et al., J. Am. Chem. Soc., 1985, Vol. 107, pp. 7219-7221.

Although the above-mentioned articles suggest that the active part of the catalyst is an ion pair, especially such a pair of ions, which contains a component with a group IV-B formula. As a cation or its decomposition product, and these references suggest that using the knowledge of the chemistry of coordination compounds, it is possible to to form such an active part of the catalyst, then all articles about the use of a Lewis acid catalyst or for the preparation of, or to stabilize the active part of the ionic catalyst. The active catalyst is of course obtained by a reaction of the type: Lewis acid - Lewis base, carried out between two inert components (Mtalocene and AlkyogUnium compound), reaching the mole-equilibrium with an inert, clearly inactive adduct and an ion pair, supposedly active catalyst. As a result of this equilibrium, competition arises for the anion which must be present in order to stabilize the active part of the catalyst catalyst. Such an equilibrium is, of course, reversible, and such reversal will deactivate the catalyst. Moreover, the above-mentioned catalytic systems are susceptible to poisoning by alkaline impurities present in the system. In addition, many, if not all, of the Lewws acids considered so far used in the soluble Ziegler-Natta type catalyst systems are chain transfer agents as a result, unirmcOliaia efficiently regulates the molecular weight of the polymer as a product and molecular weight distribution. Moreover, the catalyst systems proposed so far do not generally facilitate the derivation of a large amount of many different monomers or the random decomposition of such monomers when used in end-to-end processes, and in particular in electrolysis and oC-olefin processes. Finally, most, if not all, of the cocatalyst <in alkiśc> nrtaśoatch considered is highly pyrophoric and, consequently, unsafe to use.

The above-mentioned catalytic systems are not highly active, nor are they generally active when zirconium or hafnium is used as a Group IV-B meal.

Recently, however, it has been found that active Ziegler-Natta type catalysts can be prepared when Group IV-B bis / cyclopentadimyl / metal compounds, including zirconium and hafnium, are used together with alumoxanes. As is known, these systems, especially those containing zircon, offer several distinct advantages, such as significantly higher activities than the previously mentioned bis / cyclopeitadirnyl / titanium catalysts and the production of polymers with a narrower molecular weight distribution than when conventional Zieglm-Natta catalysts are used. . These latter developed catalytic systems still, however, yield relatively low molecular weight calcium products. Moreover, these recently developed catalyst systems did not have an effect on the amount of comonomer incorporated in the copolymer or the relative distribution of such rhamnon therein. These systems are also susceptible to poisoning when alkaline contaminants are present and require an undesirable excess of alumoxane to be effective.

Compounds based on bis / ctbprntadiriyl / hafiu, used with cocatalysts based on alumoxane, gave little advantage compared to the analogous catalysts bis / cyclopeitadiriyl / tyaio <atftmi or iis / cycloir or the random nature of the comonoime introduction. This fact was revealed by ΟίθϋΗί, Nicoletti and IMzzochi, J. Polym. Sci., Polyra. Chem. 1985, Vol. 23, pp. 2117-2133 who argued that the rates of ethylene polymerization against compounds based on bis / htklśpeitadieiylś / hafnium were 5 to 10 times lower than the rates of polymerizahi for similar compounds based on bis / cyclopeitadieiylś / -cyΓkoiu, while a slight difference between the two catalysts, compare the molecular ms of the polymer obtained with their help. 5th European Patent Application No. 200 351 A2 of 1986. it was revealed that in kśIP:> imryszahi of ethylene and propylene there was little difference between the compounds

159 196 bis (cyclopentadienyl) titanium, zirconium and hafnium in both molecular pathways of the polymer and molecular race distributions or in the ability to introduce propylene at random. Recently, Ewen et al. Disclosed in J. Am Chem. So., 1987, Vol. 109, pp. 6544-6545, that chiral mthalocene hafnium compounds were used with a tlumoxane-based cocatalyst made it possible to obtain an isotactic polypropylene of a higher molecular race than was the case with analogous chiral mtalocene zirconium compounds.

In view of the few disadvantages of the coordination catalyst systems discussed above, the need for an improved totalizer system that:

/ l / um ^ w ^! better regulation of molecular weight and molecular race distribution;

/ 2 / is not amenable to activation equilibrium / 3 / does not require the use of an undesirable cocatalyst.

It is also considered obvious the need to find a catalyst system which will facilitate the production of higher molecular grade polymeric products, facilitate the incorporation of more comonomer into the copolymer, and improve the relative comonomer distribution of such copolymers.

Otecmle found that some of the above-mentioned and other disadvantages of the known ionic olefin polymerization catalysts can be avoided or altered by all the ionic catalysts prepared according to the present invention.

It is also an object of the invention to produce a catalyst that does not undergo ionic imbalance. Yet another object of the invention is to produce a catalyst that can provide better control of the molecular weight of the product produced and a better molecular weight distribution, and such a catalyst that can be used with a lower risk of fire.

Another object of the invention is to prepare certain catalysts, in particular certain hafnium-containing catalysts, which lead to polymers of relatively high molecular species, especially hafnium-containing catalytes, which result in copolymers containing relatively large amounts of multiple ktmol. , separated at least in a manner similar to randomness. The invention makes it possible to obtain products produced with the aid of these catheters, having relatively narrow molecular race distributions and free from certain meal impurities.

The above-mentioned and still other objects and advantages of the present invention will become apparent from the description and examples set forth below.

According to the invention, the above-mentioned and other objects and advantages are achieved with and with the use of a catalyst made by combining at least two components. The first of these components is a bis (cyclopentadienylene / Group IV-B metal compound) compound containing at least one ligand which will bind to the second component or at least a portion thereof, such as the cationic portion.

The second of these components is a cation-containing ion-exchange compound that will irreversibly react with one or more lg-andes of a group IV-B metal compound (first component) and an anion, which is a single co-ordination complex containing lipt: phytate radicals bound to the centrate a metal or non-metal atom carrying and shielding the charge. This anion is spatially large, mobile, and stable to any recess in which the cation from the second component is involved. The charged metal or non-natal is a boron atom, the complex of which is not hydrolyzed in aqueous solutions. By combining the first component with the second component, the cation of the second component reacts with one of the U-ands in the first component, thereby producing an ion pair consisting of a group IV-B metal cation with an forral coordination number of 3 and a valency of +4. and the above-mentioned anion which is compatible with the k-Won

159 196 of a metal formed of and not coordinating with the first component. The anion of the second compound must be able to stabilize the Group IV-B mmeal complex cation without affecting the ability of the Group IV-B meeal cation or its decomposition product to function as a catalyst, and must be mobile enough to allow for displacement by olefin, diuoefin or acetoene unsaturated during polymerization ·

For example, Bochmann and Wilson described / J. Chem. Soc., Chem. Comm. 1986, pp. 1610-1611 (le bis (cycloi ntadienyl) wwumeeyl titanium reacts with tetrafluoroborate to form bis (cyclopeitadienyl) mtylotytan tetrafluoroborate. The anion is not, however, sufficiently mobile to be passed ^^ mi ^^^^ cot ^ r ^ y ^ m by ethylene.

As indicated previously, the present invention relates to a process for the preparation of such catalysts !, which are especially useful for the polymerization of cC-olefins, diuoefins and acetylene unsaturated monomer. either alone or in combination with other β-olephyrs, diuoephyrs and / or other unsaturated monomees. The catalysts of the invention are prepared by combining at least one first compound, which is a bis / cyclopentadienyl / metal derivative from group IV-B of the Periodic Table of the Element !, containing at least one ligand which will bind to the cathone of the second compound, the former being the compound is capable of creating a cation with a formal coordinating number r! raj 3 and a valence of different +4, and what is equal to one second of the ego of the compound, which is a salt containing a proton donor cation which will irreversibly bind to the said at least One Ugirnd (substituent) released by said Group IV-B metal compound and an anion which is a single coordination complex having a charged core, and which anion is zar! no spatially duly and labile, compatible with the katooram of the metal from group IV-B, formed from the first component and is non-coordinating with it and is capable of stabilizing the Group IV-B mmeal cation without affecting the ability of the Group IV-B metal cation or its decomposition product to polymerize - olefins, diolefins and / or unsaturated acetogen monomer! .

Wherever the Periodic Table of the Elements is mentioned, it is the Periodic Table of the Elements, published with copyright protection by CTC Fress, Inc., 1984 R! Niel by the group or groups mentioned herein as a group or groups. or groups from this Periodic Table of Elements !.

A compatible non-coordinating anion as used herein denotes an anion which either does not coordinate the cation in question, or which is fairly weakly bound to it, thus remaining motile enough to be displaced by a neutral Lewis base. it functions as a stabilizing anion in the catalyst system according to the invention and does not transfer an anionic substituent or its fragment to said cation, thereby forming a neutral meal price compound with four coordination bonds and a neutral by-product, rntalic or non-sealant. Compatible anions are anions which do not degrade to the neutral state when the initially formed kommlex decomposes. The expression non-metal used in the description refers to boron, which has the ability to semi-mimic.

Similar lists could be drawn up for the purpose of presenting bis (cycloptadiethyl) hafnium and bis (cyclopttadiene) titanium compounds, but since they would be almost identical to the list already presented above for bis (cyclopntadiethyl) zirconium compounds, such lists are unnecessary for the fertile disclosure of the essence of the invention. . However, it will be appreciated by those skilled in the art that there are no known compounds of bis (cyclpntadignyl) hafnium and bis (ckklopntadienyl) tktat corresponding to some of the bis (ckkllpntadienyl) zirconium compounds listed above.

The other bis (ckklopntadienylode) hajt compounds and other bis (ckklopttadignylode) tktat compounds and other bis (ckklopntadienylode) cyanot compounds which are useful in the catalyst classes of the invention will of course be known in the art.

Compounds useful as a second component in the preparation of the catalyst of the invention will contain a cation which is a Brbnsted acid capable of providing a proton and a compatible non-coordinating anion containing a single coordination complex containing a meealic or non-metallic core bearing a charge, which anion. it is relatively large (spatially), capable of stabilizing the active part of the catalyst (cation from group IV-B), formed by combining two compounds, the exchanged anion will be sufficiently labile for substrate displacement! olefinic, diolefinic and acetylically unsaturated.

Examples to illustrate boron compounds that can be used as a second component in the catalysis production process. The breakout method, but not limited to these, are the trialiylammonium salts, such as triethylammonium salt, boron tetra (phenyl), boron tetra (phenyl), tCUjruCylammonium tetra o-tolioo) boron, tri-boots Ooam tetra (]: e; ntafrzozffenylo) bzΓr, tΓUjpzocyOoamamZowa tetaa (o, p-Wvιuaethylpheylz) borr, tru) UuCylammonium tetoaam, m-diIϊlalyCophenyl) boΓr, tΓU) ruCyloaα] tetaa (p-rrafflurzamethylphenyl) boron -toliZo) boron and the like; Ν, Ν-D-Coonelinium-hydrate salts such as N, N-wipatyCognilinium tetra (eenylboron, N, N-diethyl) tetrapheneylboron salt, N, N-2,4,6-pentamethylailinium salt and the like; dialkylammonium salts such as tetrapheneyl ammonium diisopropyl ammonium salt, phenyl boron dicyclzhexylaaseide and the like;

and salts of tri8] yZfZofZeiżoua tetrafeenyl boron, tri (methylpheyl) phoffonoic tetrapheneylboron, tri (Invratylzphenyl) phofOonzooa tetra (feeylz) bison and the like.

In general, when most of the first relationship! the above mentioned can be combined with most of the other compounds! as defined above for the preparation of an active olefin polymerization catalyst, it is important for the continuation of the polyurethane process and that either the metal cation initially formed from the food component or the decomposition product thereof is a relatively catalyst. It is also important that the anion of the second compound is resistant to hydrolysis when the ammonium salt is used. Furthermore, it is important that the acidity of the second compound is sufficient with respect to the first compound to facilitate the transfer of the required proton. Conversely, the basicity of the mtallic complex must also be sufficient to facilitate the transfer of the necessary proton. Certain compounds of m1, for example bis (ptntametclocckloptnt ^ dienyZo) diTOtclohafnium, as an illustrative but not limiting example - are resistant to reaction with all but the strongest Brfnsted acids, and are therefore not suitable as a first ingredient for the preparation of catalysis! according to the invention. In general, etal bisCyclopentadienyl compounds which can be hydrolyzed in aqueous solutions are considered suitable as the first component for the preparation of the catalysts described herein.

Regarding the combination of the first (mmeal-containing) component with the second component to form a catalyst according to the lagging process, it should be noted that the two compounds combined to obtain the active catalyst must be selected so as to avoid transfer of part of the anion, especially the aryl group, to the cation. mesl, which would lead to the formation of a catalytically inactive product.

This can be done by means of a steric hindrance resulting from substitutions on the carbon atoms of the acklzltntαdienyl group and substitutions on the carbon atoms of the arzmtic group of the anion. This makes the compounds (first components) containing cyclopentadiene radicals ιμΚβυγμΟπιι substituted with hydrocarbon groups can be effectively used with the second compounds to a greater extent than would be the case with the compound! of mtal (first components) containing many substituted cyclopentadienyl radicals. However, when the number and size of substitutions at cckloleetαdienZ radicals decrease, the more

159 Effective catalysts will be obtained with second anion-containing compounds that are more resistant to degradation, for example, those having substituents on the ortho positions of the phenyl rings. Another means of rendering the anion more resistant to degradation is the use of vanion with fluorine substitutions, especially i-dfluorine substitutions. Fluorine-substituted stabilizing anions can therefore be used more widely with mttli compounds (first components).

In general, catalysts can be prepared by combining the two components - in a suitable solvent ranging from room temperature to 60 ° C.

The catalyst can be used to polymerize the oC-olefins and / kb of unsaturated monomers of the ajttyeen series having from 2 to about 18 carbon atoms and / kb of diuoefins of from 4 to about 18 carbon atoms, either alone or in combination. The catalyst can also be used for the polymethesis of cC-olefins, diuoefins, and / kb acetoenically unsaturated monomers in combination with other unsaturated ιηοηοπ ^ ηΐ. In general, polymerization can be carried out under conditions well known in the art.

Of course, it is noteworthy that the catalyst system can be formed in situ if its components are introduced directly into the reaction space in which the polymerization process takes place and a suitable solvent or diluent, including concentrated monoirer, is used in the process.

Preferably, however, the catalysts are prepared in a separate step in a suitable solvent before it is fed to the polymer / green step. Although catalysts do not exhibit pyrophoric properties, their components are for both moisture and oxygen and should be kept and transported in a moral atmosphere, for example nitrogen, argon or helium.

As indicated above, the catalysts are prepared according to the present invention preferably in a suitable solvent or diluent. Suitable solvents or diluents can be any of the solvents known in the art which are useful in the polymerization of olelins, two or two non-volatile monomers. From] p:) some solvents are therefore straight chain and branched hydrocarbons such as isobutane, butane, pentane, hexane, heptane, octane and the like; cyclic and cyclic hydrocarbons such as cyclohexane, cycloheptane, methylcyclohexa, methylcyclohexa, and the like, and unsubstituted and alkyl-substituted aromatics such as benzene, toluene, xylene and the like. Also suitable solvents are liquid olefins which can act as monomers or chambers, such as ethylene, propylene, butadiene, cyc ^^ nie, i-hexene, 3-methyl-1-] E: tοteο- 4-methylZo-e-peοteο , Α-hexadiene, 1-octene, i-deron and the like.

Moreover, Οάρο! Ί ,ηίιηί solvents are basic solvents which are generally unsuitable as solvents in polymerization carried out with convolutional Ziegler-Natta catalysts and polythorizates of the Ziegler-Natta type, such as jhllrobeοzeο.

While it is not the intention of the inventors to be bound by any particular theory, they believe that when the two compounds used in the preparation of catalysis and the process of the invention are combined in a suitable solvent or diluent, all or a portion of the cation of the second compound (acid proton) is combined with one of the meeal-containing substituents of the first component. When the first component has the formula corresponding to the general formula given above - /_J.iOp / - * K₁X2, a neutral compound is released which either remains in solution or is evolved as a gas. Therefore, it should be stated that if either X ^ or ^ in the fifth imeal-containing component is hydrogen, hydrogen gas may be produced. Similarly, if either X 1 or 2 is methyl, methane may evolve as a gas. In the case where the first component has the formula given in the following general formulas, One of the substituents w containing meeal

159 The 196 (first) component is protonated and, generally, no substituent is separated from the metal.

It is preferred that the molar ratio of the first component to the second component is 1: 1 or greater. The conjugate base of the cation of the second compound, if it remains so, will be the neutral compound that will remain in solution or complex with the metal cation formed, although, in general, the second compound is selected so as to optionally bind to the volatile conjugate base of the metal it was weak or not there at all. Thus, as the spatial size of this conjugate base increases, it will simply remain in solution without affecting the active catalyst. Similarly, if the cathion of the second compound is-t Tralkylionium ion, this ion □ enters the hydrogen atom to form hydrogen gas, mtan, or the like, and the conjugate base of the cation will be a tetranium amine. Similarly, if the catoon were a phosphonium ion, substituted with a hydrocarbon group, containing at least one reactive proton, which is essential for the production, the conjugate base of the cation would be phosphine.

It should be assumed that when one of the substituents (of the first compound) containing meeal (ligand) is present, the nitcoir anion initially present in the second compound used for the preparation of the catalyst will combine with it and have a stabilizing effect on either the metal cation obtained from the first component, formally m with a coordinate number of 5 and a valence of +4, or the product of its decomposition.

The metal cation and the non-conductive enion will remain so bound until the catalyst comes into contact with the one or more olefim, two and / or acetylenic thietsaturated monomers either alone or in combination with one or other monoiOfs or other neutral Lewis base . As indicated above, the anion contained in the second compound must be sufficiently labile to allow for rapid displacement by olefins, diuoefins or acetytenically unsaturated montmos in order to facilitate polymrysilia Chemical reactions that occur in the process ^^ t: w ^ and ^: ^ i ^ i ^: ia katalίaaioó &lt;In the process of the invention, when a preferred boron-containing compound is used as the second component, it can be represented by the following general formulas:

In the above reaction equations, the numbers are shown in conjunction with the general equations for useful metU metU compounds of group IV-B (first components). In general, the stability and the formation rate of the products in the above reaction equations, especially of the metal cation, will vary with the choice of the solvent, the acidity of the selected / L'-H_7, especially the L'-anion, the temperature at which the reaction will be completed, and a specific dicyclopentate dittyl derivative

159 Generally selected, the initially formed Ion pair will be an active polymerization catalyst and will polymerize oG-olefins, diuoefins and acetytenically unsaturated monomers, either alone or in combination with other monoliths. In some cases, however, the starting alu cation will decompose to provide an active polymerization catalyst.

As previously indicated, most of the first compounds defined will combine with most of the second compounds defined above to form an active catalyst, especially an active polymerization catalyst. The presently active part of the catalyst, however, is not always definitively permanent in order to allow its separation and subsequent identification. Beyond this, and while many of the initially formed metal shapes are relatively stable, it is evident that the initially formed ι ^ βΐυ cation often breaks down into one or more other active parts.

It is assumed that the active parts of the catalyst which have not been characterized, including the active decomposition products, are of the same type as those which have been isolated and fully characterized, or at least have retained the essential ionic structure required for their functioning as a catalyst. More specifically, it can be assumed that the active parts of the catalyst which have not been isolated, including active decomposition products, are of the same type as the separated and schaakteΓytowair parts of the active catalyst in that they contain a bis (cyclopentadienyl) metal center which it remains carbonic, unsaturated, and has a meeta-carbon bond that is reactive with olefirs, di-doephyrs, and acetylenically unsaturated compounds. In addition, it can be assumed that the decomposition products may react with hydrogen gas to bring into a common equilibrium state including the cathonic hydride complex / ~ Cp'Cp - W 7 + Χ ".

This behavior is the best illustrated in the perαlkitczkktorenαadtiyyOiwym system, where t ^^ phenyl ^ -bor is used as the second component. For example, the reaction of Cp * 2 ZrM ^ (where Cp "= C ^ Me ^) and / Bu-jNH_7 + - / B (Fh ') ^ _7, where Fh' = phenyl or ^ rn-alkylfmyl with hydrogen or an alkyl group in the para position, in toluene it gives / Cp ^ Zi —'e_jA / "B (Fh 7", which is unstable and decomposes losing rntane, giving a single active product, catalytic converter. The deep red product was completely characterized by NMR spectroscopy and single crystal radiation by <RTI ID = 0.0> n ^ X </RTI>. The general structure of this type of zwitterionic ion catalyst is represented by the formula 1, wherein Cp- is peaalkito-t <xist8wio and cycltpentadiaisltwy radical, each of the alkyl substituents being the same or different alkyl radical with 1-6 carbon atoms, most preferably the same or a different radical Clkitoiz having 1-4 carbon atoms; B is boron, Zr is zirconium, Fh 'is phenyl or phenyl substituted with alkyl group, and each of the three Fh' may be the same or different, and the alkyl substituents may contain 1-6 carbon atoms, most preferably 1 - 4 carbon atoms and R is hydrogen or an alkyl group containing from 1 to 6 carbon atoms, most preferably from 1 to 4 carbon atoms.

The study of excess hydrogen gas to a toluene solution containing the above-mentioned perityl-substituent ion zwitterionic catalyst causes a rapid reaction, which is recognized by the color change from red to yellow, and in concentrated solutions, due to the formation of a yellow precipitate. Removal of hydrogen from the system results in the regeneration of the initial joίowo-Ziubieguitiego catalyst with high efficiency. Without wishing to be bound by any particular theory, it can be assumed that the reaction of hydrogen with the ionic zwitterionic catalίcatoeii leads to the formation of Γ ^C.P * 2 ZrH fi / jB (Ph ') z_7.' The reversible nature of this reaction, together with other spectroscopic evidence, suggests that the hydride cation is in chemical equilibrium with a compound of a zwitterionic nature.

In accordance with the above, stable polymerization catalysts were prepared by reacting bis (] r ^ Γmethytocyte ^ Naadtisite) and tetra-methyltisctn with tetra (n-butyl) boron tri (n-butyO) and pi] onium salt and salt tΓÓjin-luZyto) and tetra

159 196 (p-ethylphenyl) boron. A stable polymerization catalyst was also prepared by reacting bis (ethyl tetramethylcyclopentadienyl] dimethyl zirconium with a tri (n-butyl) ammonium salt of tetra (p-tolio) boron. 0 ° to about 100 ° C.

Based on this, the eyes * of the fact that stable ion-zwitterionic catalysts can also be prepared by using bis (Ii ^ hydrocarboncyclopentadineinyl) dual-compound- and ZwruilzltlorClnl compounds by combining them with ammonium salts of unsubstituted or substituted triethyl para-anion btliwegl.

In general, the stable catalyst prepared by the process of the invention can be separated from the solvent and stored for further use. However, the stable catalyst will generally remain in solution until its final use in the polymerization process of olefins, di ^ ^ and / or acetylenically unsaturated monomers. Alternatively, each of the kataliraOtó! The process according to the invention can be left in solution for further use or used as a catalyst for pllymyrication directly after formation. Moreover, as stated above, the catalyst can be prepared in situ during the polyurethane reaction by introducing separate components into the polymerization reactor, where the components are these will come into contact and react to form a catalyst according to the invention.

If the ratio of the first compound to the second compound is 1: 1, at concentrations below about B3 *⁵ K, ^katalysis^volot part^ęone hundred is not active in the process ^poliί; ΓyzacOi olefi ^ n. While it is not intended by the inventors to be bound by any particular theory, it may be surmised that inadvertent oxygen or moisture, contained in the diluent or monoramees, may de- termine the catalyst.

However, when the ratio of the first compound to the second compound is from 2: 1 to 10: 1 or greater^, then ^ last.eppo comp^dno^kor maybe ^be lighter than^{with 10} &amp; M.

If hafnium-containing compounds are used first and are reacted with the burea-containing and acidic ammonium compounds used as second compounds - for example the salt of 'tΓjin-UuCyl) allonloaa tetra (pentafluoΓophenyl) blru - and such a catalyst is used in the pan ^ erzzac process ! then you can observe induce periods ranging from about 1 to about 15 minutes lu? more before the monornorm download begins. This phenomenon is more of a

clear, when the concentration of the hafnium compound is less than about 10 M, and the concentration of the second component is: less than^with about ¹0^{_5 M.}; solutions o^withch^ym concentration of catalyst part^bitsit does not show the inZU &lt;cOi period. This can also be seen when compounds containing c6con are used first, then later^drugir^gThe formula is about 10 * ^ M or m ^^. It can be assumed that the type of catalyst formed decomposes in the polymerization process to form a totalitically inactive compound containing a meal and regenerating the same or a different second component. This new second component activates the first component, present in any excess, to regenerate the active catalyst. It can also be assumed; that increasing the catalyst concentration or using second components containing more acidic ammonium cations, or shorter this induction period, or eliminating it from the soup.

In general and has been shown, the improved catalyst made according to the invention will cause the polymerization of mefins, di-efins and / uub aoithienically unsaturated monoramers, either alone or in combination with other oleins and / u ^ b other unsaturated ιηοηοπ ^ Βΐηί under well-defined conditions. known from the prior art for Ziegler-Natta. In the polymerization process with C. catalyst prepared according to the invention, the molecular race turns out to be a function of both the catalyst concentration and the temperature and pressure of the polymer. Polymers produced with such a catalyst, when produced without significant mmsy transport effects, will generally have relatively narrow race molecular distributions.

159 196

Certain catalysts according to the invention, especially those based on hafnium-containing metallocene compounds - for example the catalyst obtained by reaction of bis (cyclopentadiene) dimethylhafnium and trisubstituted ammonium tetra (pentafluorophenyl) boron - when used as described for polymerization and copolymerization of oG-olefins, diulefins and / or acetylenically unsaturated monomers, in the absence of a charge transfer agent, can lead to the production of extremely high molecular weight polymers and copolymers having relatively narrow molecular race distributions. In this respect, it should be noted that with the participation of kαtαlCzaloΓiw produced according to the formula, it is possible to produce copolymers and homopommers having molecular masses of up to about 2.10θ and the distribution^y masses part^andin ^ anicacii from n^knłn 1.5 ^doolto ^ ¹5. However, substituents on cyclopentadiene radicals can have a profound effect on the molecular weights of the polymer.

Kaaalizatory manu Arzana method according to wyidazku comprises hereby a first constituent or a pure enantiomer or a racemic mixture of the two π ^ ^ ^ Οϋ ίΜ rigid, chiral mealncenowlgo may cause prnchimllnych polymerization of olefin (propylene and wyższychd-olefins) to isotactic polymers. Bis (cycloalkyl) metal compounds in which each of the hyZlopentadienyl radicals is substituted and contains a covalent bridging group between two cyZlopentadienyl radicals are particularly suitable for isotactic polymerizations of this type.

A particularly unexpected feature of some of the Wί catalyst obtained by the process of the invention, especially those based on hafnium-containing metallocene compounds in combination with a second boron-containing silicon dioxide, is that when the catalysts are used for the copolymerization of oC-olefins either alone or in combination with , the amount of higher molecular weight olefin or dipefin incorporated into the copolymer is significantly greater compared to the otic copolymers with most conventional Ziegler-Natta-type kαtalCOr and bisyclopentadienyl catalysts. The relative rates of reaction of ethylene and higher oC-olefins with the above-mentioned catalysts prepared according to the invention based on hafnium are more similar than those of the conventional ZαtalCzaOo and Ziegler-Natta with group IV-B mtals. The monomer distribution in the copolymers made with ZatαlCzanoi prepared according to the invention, especially for the lower oC-oleins and the lower diphthins, will range from nearly perfect, progressing sequentially to statistically random.

In general, the catalysts can be selected to produce polymeric products which will be devoid of some trace ιμΙα !. typically found in polymers produced with ZatαlCzalró &lt;wι of the Ziegler-Natta type, such as aluminum, ragnesium, etc.

The polymer products prepared with the aid of the catalysts of the invention should therefore have a wider range of yields than polymers made with the participation of many Ziegler-Natta-type Ziegler-Natta-type Ziegler-Natta compounds containing a metal alkyl, such as an aluminum alkyl.

Also, unlike the polymers previously produced by conventional kαtals and Zegler-Kerosene polymerizations, polymers produced with the zwitterionic ZatαlCαanrói in the absence of hydrogen or other chain-terminating reagents contain mainly intrinsic rather than terminal unsaturation. In this regard, it should be noted that if the terminal carbon atom in the polymer chain were number 1, the unsaturation found in the polymer made by the inventive catalyst process would be in the 2,3 position rather than the more traditional 1,2 position.

In a preferred embodiment of the invention, the bis (cyclopentadienyl) methyl compound in which the ratal is titanium, zirconium and hafnium, and which compound contains two independently substituted or non-substituted hcklnpentadienyl radicals.^aboutand one or two lower alkyl substituents

159 196 Ip and / or one or two hydride substituents combine with the trisubstituted ammonium salt of substituted or unsubstituted tetra (aommstic) boron. Each of the three substituents in the ammonium cation may be the same or different from a lower alkyl or aryl radical. By lower alkyl is meant an alkali radical containing 1-4 carbon atoms. When a bis (percarbohydrocyclopentadienyl) metal compound is used as the bis (cyclopentadienyl) metal compound, an unsubstituted or partially substituted aromatic tetra (rommatic boron) salt can be used. Particularly preferred are the tri (n-butyl) ammonium tetra (phenyl) salt. boron, tri (n-butyl) ammonium, tetra (p-tolyl) boron and tri (n-butyl) iionic tetra (p-stylophenyl) boron. However, if the feast of hydrocarbon substituents in cyclopentadienyl radicals is less, use trisubstituted ammonium salts with an anion substituted in the aromatic part, especially with a pentafluoro substituted anion. Particularly preferred is the tr (n-butyl) ammonium salt of tetraapentafluorophenyl boron.

In a more preferred embodiment of the invention, bis (cykio] a! Ntrdtetyio) Wwumettlactrcon or bis (cyclopentadtenyio) dimtyloha / n is reacted with the N, N-dimethylirilinium tetra (pentafluorophenyl) boron salt to obtain the most preferred catalyst. These range from room temperature to about 60 ° C. The ingredients are preferably combined in an aromatic hydrocarbon solvent, and most preferably toluene. Nominal holding times in the range of about 10 minutes to about 18 hours are sufficient to obtain both the preferred and most preferred catalysts of the invention.

The catalyst is preferably used immediately after formulation for polymerization, lower 10 ° C - other, especially ethylene or propylene, most preferably ethylene, in the temperature range from about 0 ° C to about 100 ° C and in the pressure range from about 0.1 Wa to about 3. 5 Ma. The lila catalyst is preferably used either for the homoimmimization of ethylene or for the copolymerization of ethylene with a lower ° C olefin having 3-6 carbon atoms, thus producing a plastic or copolymer with elastomeric characteristics. Both in the preferred and most common embodiment, ιηοηοϋ ^ is maintained under the polymerization conditions, nomirally in the range from about 1 to about 60 minutes, and the catalyst is used at a concentration in the range of -5_-1 from about 10 to about 10 ml per liter of solvent.
