The present invention relates to an addition polymerization catalyst and a method for the preparation of a catalyst. The new catalyst of the invention contains a metal coordination complex with voltage in the molecule.
Due to the unusual exposure of the active metal center in the metal coordination complexes with the voltage in the molecule, the catalysts obtained from them exhibit exceptional properties. Under certain conditions, the catalysts of the invention allow the production of new olefin polymers with properties not seen before, due to their exceptional ease of polymerization of α-olefins, diolefins, aliphatic sterically hindered vinylidene monomers, vinylidene aromatic monomers and mixtures thereof.
Numerous metal coordination complexes are known, including those containing monocyclopentadienyl and substituted monocyclopentadienyl groups. The metal coordination complexes contained in the catalyst according to the invention differ from the known complexes in that the metal is bonded to a delocalized, substituted π-linked moiety in a manner that causes tension around the metal atom. Preferably the metal is attached to a cyclopentadienyl group, a substituted cyclopentadienyl group or other similar group with a η bond<sup>5</sup> and a bridge connection including other metal ligands. The complexes preferably contain metals having useful catalytic properties.
Transition metal coordination complexes, also known as corrugated complexes, are also known. Such complexes are described in Organometallics 6, 232-241 (1987).
In the patent application Ser. Amer. No. 8,800 of 30/01.87, corresponding to European Patent Publication No. 277 004, discloses certain bis (cyclopentadienyl) methyl compounds prepared by reacting a bis (cyclopentadienyl) metal complex with Bronsted acid salts containing a non-coordinating, compatible anion. The cited publications reveal that such complexes are successfully used as olefin polymerization catalysts.
However, these are not particularly effective olefin polymerization catalysts.
Previous attempts to produce copolymers of aromatic vinylidene compounds with α-olefins, in particular copolymers of styrene and ethylene, have not achieved significant incorporation of vinylidene aromatic monomer or have resulted in low molecular weight polymers. Polymer Bulletin, 20,237-241 (1988) describes a styrene ethylene random copolymer containing 1 mol% of embedded styrene. The yield of the polymer in question was 8.3 X 10<sup>_4</sup>g of polymer / mol of titanium used.

It has now been found that known addition polymerization catalysts cannot exhibit high activity and are not able to polymerize many monomers due to the lack of voltage in the molecule.
The invention relates to a catalyst that contains a metal coordination complex with a voltage in the molecule in combination with activating cocatalysts or mixtures of such compounds. Such a catalyst can be successfully used in the polymerization of additionally polymerizable monomers, in particular ethylenically unsaturated monomers.
The invention also relates to a method for preparing such catalysts.
The catalyst according to the invention consists of a) metal coordination complex of formula 2, in which R 'is in each case hydrogen or halogen or alkyl, aryl, silyl, germyl or cyano, containing up to 20 non-hydrogen atoms, or an adjacent pair the R 'group forms a cyclopentadienyl group with an indenyl, tetrahydroindenyl, fluorenyl or octahydrofluorenyl group; X is in each case coordinated hydrogen or halogen or alkyl, silyl, germyl, aryl, aryloxy, alkoxy or siloxy or an amide residue containing up to 20 non-hydrogen atoms; Y is -O-, -S-, -NR<sup>X</sup>-, -PR * - or a neutral two-electron donor ligand selected from the group consisting of ORX, SRX, NR * 2 or PRX2, M is a titanium, zirconium or hafnium atom, and Z is SiRX2, CR * 2, SiR * 2SiR * 2, CRX2CRX2 , CRX = CRX, CRX2SiRX2, GeR * 2, BRX and BR * a, where Rx is in each case hydrogen or alkyl, aryl, silyl, halogenated alkyl or halogenated aryl, containing up to 20 non-hydrogen atoms, an is equal to 1 or 2 and b) an activating cocatalyst selected from the group consisting of aluminoxanes, aluminum alkyl compounds, aluminum halides, aluminum alkyl halides, Lewis acids and non-interfering oxidizing agents and mixtures thereof.
It should be noted that in Formula 2, which represents the cyclic structure of the complex, when Y is a two-electron donor ligand, then the bond between M and Y should be accurately defined as a coordination-covalent bond. It should also be noted that the complex may exist as a dimer or in the form of a higher oligomer.
Preferably, at least one of the R ', Z or RX groups is an electron-donating moiety. Thus, very preferably Y is a nitrogen or phosphorus containing group represented by the formula -N (R) -or -P (R) -, wherein R is C 1-10 alkyl or aryl, i.e. an amide or phosphide group.
Most preferably, the complex compounds are amidosilane or amidoalkanediyl compounds of the formula III in which M is a titanium, zirconium or hafnium atom bonded with an η<sup>5</sup> with a cyclopentadienyl group, R 'is in each case a hydrogen atom or a silyl, alkyl or aryl group containing up to 10 carbon or silicon atoms; E is silicon or carbon; X is in each case coordinated hydrogen or halogen, alkyl, aryl, aryloxy or alkoxy containing up to 10 carbon atoms; m is 1 or 2 and n is 2.
Preferably, the catalyst contains a complex of formula 3 in which R 'is in each case hydrogen, C 1-6 alkyl, norbornyl, benzyl or phenyl or one or more R' attached to a cyclopentadienyl residue forms an indenyl, tetrahydroindenyl, fluorenyl or octahydrofluorenyl group with this residue , X is chlorine, bromine, iodine, C 1-6 alkyl, norbornyl, benzyl or phenyl and E, M, min are as defined above.
Particularly preferred are catalysts containing a coordination complex of formula 2 or 3 in which M is a titanium atom and the other substituents are as defined above.
Examples of the above-mentioned most preferred metal coordination compounds include those in which R 'on the amide group is methyl, ethyl, propyl, butyl, pentyl, hexyl (including its isomers), norbornyl, benzyl, phenyl R' on each cyclopentadienyl group means in each hydrogen, methyl, ethyl, propyla, butyl, pentyl, hexyl (including isomers), norbornyl, benzyl, phenyl and X is chlorine, bromine, iodine, methyl, ethyl, propyl, butyl, pentyl, hexyl (including also isomers), norbornyl, benzyl, phenyl. Specific compounds include: (tert-butylamidoKtetramethyl-n-cyclopentadienyl) -1,2-ethanediyl zirconium dichloride, (tert-butylamido) (tetramethyl-n5-cyclopentadienyl) -1,2-ethanediinediititane dichloride (methylamido) dichloromethyl<sup>5</sup>-cyclopentadienyl) -1,2-ethanediyl zirconium ((methylamidoXtetramethyl-n dichloride)<sup>5</sup>-cyclopentadienyl) -1,2-ethanediyl titanium, (ethylamido) dichloride (tetra166 689 methyl-n<sup>5</sup>-cyclopentadienyl) methylene titanium, (tert-butylamido X-dimethyl- / tetramethyl-n-dichloride<sup>5</sup>-cyclopentadienyl) silanitanium, (tert-butylamidimidomethylphthetramethyl-^ - cyclopentadienyl / silane) dibenzyl) zirconium, (benzylamido / dimethyl (tetramethyl-η) dichloride<sup>s</sup>-cyclopentadienyl) silicate, (phenylphospho / dimethyl) tetramethylene<sup>8</sup>-cyclopentanecarboxylic acid tert! opentadlenyloXsilano,<sup>/</sup>dibenzyl) zirconium.
The complexes can be prepared by contacting a metal reagent with a Group I metal derivative or a Grignard derivative of a cyclopentadienyl compound in a solvent and separating the by-product salt. Suitable solvents for making metal complexes are aliphatic or aromatic liquids such as cyclohexane, methylcyclohexane, pentane, hexane, heptane, tetrahydrofuran, diethyl ether, Ci-<sub>4</sub>monol or diethylene glycol alkyl ethers, C 1-4 alkyl mono- or dipropylene glycol ethers, benzene, toluene, xylene, ethylbenzene etc., and mixtures thereof.
According to a preferred method, the metal compound is a compound of formula MX<sub>n</sub>+ i in which M is at a lower oxidation state than in the corresponding compound MXn + 2 and than the oxidation state in the desired finished complex. A non-interfering oxidizing agent may then be used to increase the metal oxidation state. Oxidation is carried out simply by contacting the reagents with a solvent and under the same reaction conditions as in the production of the complex itself. The term "non-interfering agent" refers to a compound having an oxidizing potential sufficient to increase the metal oxidation rate without interfering with the formation of the desired complex or subsequent polymerization. AgCl is a particularly suitable non-interfering oxidizing agent.
In order to facilitate the handling of the metal compounds used according to the invention according to the formula MXn + 2, it may be advantageous to form their solid adduct first by using the appropriate coordination agent in accordance with known methods. Eg. since titanium tetrachloride is a fuming liquid that is difficult to manipulate, a TiCl adduct with ether, a tertiary amine, a tertiary phosphine or other basic nonproton compound can be prepared first. The resulting solids can be handled more easily. The preferred coordinating adduct is tetrahydrofuran.
The reactions used to form the metal complex can be carried out under heterophasic or homophasic conditions. This means that the various reactants or the resulting product need not be substantially soluble in the solvent mixture. Usually the reagents are contacted in an inert atmosphere for a few minutes to several days. If necessary, mixing can be used. The reaction temperature is generally from -90 to 150 ° C, preferably from -20 to 70 ° C.
The inventive catalysts are prepared by contacting a metal coordination complex of formula 2 as defined above with an activating cocatalyst compound selected from the group consisting of aluminoxanes, aluminum alkyl compounds, aluminum halides, aluminum alkyl halides, Lewis acids, and non-interfering oxidizing agents and mixtures thereof. in any order and in any appropriate way. Preferably, the molar ratio of the coordinating complex to the cocatalyst is from 1: 0.1 to 1:10,000. Of course, it should be understood that the catalyst system can also be generated in situ if its components are added directly to the polymerization system and the polymerization process is used a suitable solvent or diluent, including liquefied monomer. Suitable solvents include toluene, ethylbenzene, alkanes and mixtures thereof. In some cases, the catalysts can be separated from the solution and stored in an inert atmosphere before use. The components of the catalyst are sensitive to both moisture and oxygen, so that their handling and storage should take place in an inert atmosphere, e.g. in nitrogen, argon or helium, or under reduced pressure.
The catalysts of the invention are successfully used in addition polymerization to produce polymers useful as shaped articles, packaging films and upholstery foams, as well as in the modification of synthetic or natural resins.

As used herein, the term "delocalized π-linked moiety refers to an unsaturated organic moiety, e.g., one that contains an ethylene or acetylene group in which the π electrons have been given to the metal to form a bond. For example, alkene, alkenyl, alkyne, alkynyl, allyl, polyene and polynyl moieties, as well as unsaturated cyclic systems.
The term "voltage in a molecule" means that there is a forced greater exposure of the active metal center in the metal atom as a result of the presence of one or more substituents on the delocalized, π-linked moiety. Preferably, the delocalized, π-linked moiety is a cyclopentadienyl group or a substituted cyclopentadienyl group forming part of the ring structure in which the metal is attached to the adjacent covalent moiety while being associated with the delocalized π-linked moiety through η bonds<sup>5</sup>. It is understood that the corresponding bonds between the metal atom and the atoms forming part of the delocalized π-linked moiety need not be equal. This means that the metal can be symmetrically or asymmetrically π-connected to the π-linked moiety.
The geometry of the active metal center can be more accurately determined as follows. The mass center of the π-linked moiety can be defined as the average of the corresponding coordinates X, Y and Z of the centers of the atoms forming the π-linked moiety. The angle przy formed at the center of the metal between the center of mass of the π-linked moiety and each of the other ligands of the metal complex can easily be calculated by known single crystal X-ray diffraction techniques. Each of these angles can increase or decrease, depending on the molecular structure of the metal complex with voltage. Those complexes in which one or more angles θ are smaller than in a similar, suitable complex, which differs only in that the voltage-causing substituent has been replaced by a hydrogen atom, show voltage in the sense of the invention. Preferably one or more of these angles θ is reduced by at least 5%, and more preferably by 7.5% compared to the comparison complex. It is very advantageous if the average size of all angles θ between the bonds is also smaller than in the comparative complex. Most preferably, the metal coordination complex with tension is in the form of a ring structure, which means that the voltage-causing substituent is part of the ring system that includes the metal atom.
Preferably the monocyclopentadienyl metal 4 or lanthanide coordination complexes according to the invention exhibit such a voltage that the smallest angle θ is smaller than 115 °, even more preferably smaller than 110 °, and most preferably smaller than 105 °.

Hydrogen can additionally be used to regulate molecular weight causing chain termination in a known manner. The catalyst can be used as such or supported on a suitable support such as alumina, MgCl2 or silica, thus forming a heterophasic supported catalyst. If required, a solvent can be used. Suitable solvents include toluene, ethylbenzene, and excess vinylidene or olefinic aromatic monomer.

It is understood that the metal complex may undergo various transformations or form intermediate variants before or during polymerization. Accordingly, other precursors could probably be used to obtain the same catalytic forms as mentioned above, without departing from the scope of the invention.
The resulting polymer product is isolated by centrifugation or another suitable method. Additives and auxiliaries may be incorporated into the polymers of the invention to obtain the desired properties. Suitable additives include pigments, UV absorbers, anti-oxidants, blowing agents, lubricants, plasticizers, photosensitizers and mixtures thereof.
In the preparation of copolymers containing aromatic vinylidene monomers or aliphatic sterically hindered vinylidene monomers, it is desirable to simultaneously use a comonomer that is α-olefin without pronounced steroidal hindrance. Without being bound by any particular theory of action, it is believed that this is due to the fact that the active center is filled as a result of incorporation of a vinyl compound with spatial hindrance, so that it is impossible for another molecule of a vinyl compound with spatial hindrance to take part in the polymerization as the next monomer in sequence. After incorporation of one or more non-hindered vinyl olefins, the active center will again become available for hindered vinyl monomer. To a limited extent, however, the aromatic vinylidene monomer or sterically blocked vinylic monomer can be embedded in the polymer chain in an inverted position, so that 2 methylene groups are obtained between the substituted moieties in the polymer chain.
Preferably the molecular weight of such polymers, Mw is over 13,000, even more preferably over 20,000 and most preferably over 30,000. Equally preferably such polymers have a melt index (I2), ASTM D-1238, procedure A, conditions E, below 125, even more preferably from 0.01 to 100, and most preferably from 0.1 to 10.
By using the aforementioned catalyst system containing the voltage coordination complex, copolymers containing relatively large volumes or sterically hindered monomers can be produced in a substantially random manner, in small amounts and in larger amounts, according to the principle of ordered insertion. Copolymers of α-olefins, in particular ethylene with a sterically hindered aliphatic vinyl compound or with an aromatic vinylidene monomer, can more accurately be called "pseudostatic" copolymers. This means that the copolymers do not contain clear blocks of any of the monomers, although the insertion of individual monomers is limited according to certain rules.
These principles were deduced on the basis of some experimental details obtained from the analysis of polymers. The polymers were analyzed by spectroscopy 1<sup>3</sup>C NMR at 130 ° C on a Varian VXR-300 at 75.4 MHz. Samples of 200-250 mg of polymer were dissolved in 15 ml of a hot mixture of o-dichlorobenzene-1,1,2,2-tetrachloroethane-d2 (about 70/30 by volume) containing about 0.05 molar chromium (III) tris (acetylacetonate). Part of the resulting solution was loaded onto a 10 mm NMR tube. - The parameters and measurement conditions were as follows: spectrum width 16 500 Hz; access time 0.090 s; pulse width of 36 °; 1.0 g delay with the decoupled masked during the delay; size FT 32 K; the number of sweeps - over 30,000; 3 Hz line extension. Spectra were recorded relative to tetrachloroethane-d2 (δ 73.77 ppm, TMS scale).
As a result, without being bound by any particular theory, the results of the above experiments indicate that the special feature of pseudostatic copolymers is that all phenyl groups or large volume groups that are spatial hindrances, constituting substituents on the polymer chain, are separated by two or more groups methylene. other
166 In other words, the polymers containing sterically hindered monomer according to the invention can be represented by the following general formula 4 (using, for example, styrene as hindered monomer), with j, k and 1> 1 in this formula.
More specifically explaining the experimental and theoretical results without binding to any particular theory, it can be concluded that during the addition polymerization reaction using the catalyst according to the invention, if the monomer with sterically hindered insertion occurs into the growing polymer chain, the next building up monomer must be ethylene or hindered monomer that builds up inversely, i.e. with a tail-to-tail connection. This is shown below in the diagram for spatial hindered vinyl monomer, where M is the center of the catalytic metal, HG is the hindered group, and P is the growing polymer chain.
During the polymerization reaction, ethylene insertion can occur at any time. After an inverted or tail-to-tail insertion of the hindered monomer, the next monomer must be ethylene, because the insertion of another hindered monomer at this point would have to cause the substituents constituting the hindrance to be located closer than the minimum distance mentioned above. The consequence of such polymerization principles is that the catalysts according to the invention do not significantly homopolymerize styrene, while a mixture of ethylene and styrene polymerizes very quickly, whereby copolymers with a high styrene content (up to 50 mole% styrene) can be obtained.
In order to more accurately illustrate the description of the olefin / spatial hindrance copolymer, according to the invention, a computerized polymerization reaction model was used to calculate the expected spectrum 1<sup>3</sup>C NMR of the polymer produced. A computer program with a statistical number generator was used to select an α-olefin or sterically hindered monomer as a monomer to be incorporated into the growing polymer chain, after which the amount of each type of signal was calculated 1<sup>3</sup>C NMR sent as a result of such insertion. Polymers were computer generated by repeating the above procedure for 10,000 or more insertions, followed by the calculated spectrum 1<sup>3</sup>C NMR was compared with real experimental spectrum 1<sup>3</sup>NMR of pseudostatic ethylene / styrene copolymers according to the invention.
Computer simulations of polymer and obtained spectrum 1<sup>3</sup>The calculated NMR of the calculated pseudostatic ethylene / styrene copolymers was made on the assumption that if an insertion of styrene monomer into the growing polymer chain occurs, then the next incorporated monomer must be ethylene or styrene inversely incorporated, with a tail-to-tail connection. Optimal agreement between the experimental and calculated spectra was achieved when approximately 15% of the styrene insertion was tail-to-tail. Observed and computational spectra 1<sup>3</sup>C NMR for such pseudostatic ethylene / styrene copolymers containing 1.4, 4.8, 9.0, 13.37 and 47 mole% styrene are shown in Figures 8-13. In all cases there is excellent agreement between observed and calculated spectrum.
Then computer simulation and its spectrum were performed 1<sup>3</sup>C NMR in the case of a fully static α-oleffn <a / sterically hindered monomer, with no restrictions on insertion of sterically hindered monomer. In other words, spatial hindrance monomer insertion into the growing polymer chain was possible after spatial hindrance monomer insertion if the random number generator chose hindrance monomer as the next monomer to be incorporated. The calculated spectra of such completely statistical copolymers are not consistent with the observed spectra 1<sup>3</sup>C NMR as shown in Figure 14 for an ethylene / styrene copolymer containing 37 mole% styrene.
Before polymerization, the monomers and optionally solvents can be purified by distillation under reduced pressure and / or contact with molecular sieves, silica or alumina to remove impurities. Additionally, reactive sheathing agents such as trialkylaluminum compounds, alkali metals and their alloys, in particular Na / K, can be used to remove impurities.
Suitable aromatic vinylidene monomers which may be used include styrene and also α-methylstyrene, styrene derivatives substituted with a C 1-4 alkyl or phenyl ring, such as o-, m- and p-methylstyrene, or mixtures thereof, ring halogenated styrenes, vinylbenzocyclobutanes and divinylbenzene. A preferred aromatic vinylidene monomer is styrene.

When polymerizing aromatic vinylidene monomers or aliphatic sterically hindered vinylidene monomers with olefins, the monomers are preferably mixed in such a proportion that the obtained polymer has a content of aromatic vinylidene monomer (or aliphatic hindered vinylidene monomer) of at least 1.0 mol% more preferably from 1.5 to less than 50 mole%, very preferably from 5.0 to 48 mole%, and most preferably from 8.0 to 47 mole%. Preferred conditions for carrying out such polymerization reactions are atmospheric pressure to 10 MPa and temperature from 30 to 200 ° C. As a result of polymerization at temperatures above the autopolymerization temperature of the corresponding monomers, small amounts of homopolymerization polymerization products can be obtained as a result of free radical polymerization.
Certain polymers made using the catalyst of the invention, especially copolymers of ethylene and α-olefin other than ethylene, have unique rheological properties. In particular, the polymers (hereinafter referred to as flexible polyethylenes, E1PE) have been found to be less Newtonian than linear polyethylene resins with similar olefin content produced in the usual way. The polymers also have a higher modulus of elasticity, especially at higher flow rates, compared to conventional polymers. Due to this property, the resin is particularly useful for the production of films, foams and shaped products, e.g. by blow molding techniques. This phenomenon can be illustrated in detail with the help of Fig. 16, which shows the complex viscosity η *, measured in poise at 190 ° C as a function of shear rate, ω, measured in rad / s, for a typical ethylene 1-octene copolymer, type E1PE, according to the invention. The slope of this curve indicates that the alloy is highly non-Newtonian. The real values η * and ω used to construct the chart were as follows:

Improved melt-blow processing characteristics provide a tg 0.1 to 3.0 size at shear rates from 0.01 to 10 rad / s.

For comparative purposes, typical properties of η * and ω for a polyethylene resin obtained in the usual way are shown in Figure 17.
It can easily be said that E1PE resins have a higher elastic modulus in the alloy. In particular, E1PE resins have a melt index (I2), ASTM D-1238, procedure A, conditions E, below 200, preferably below 125, and most preferably below 50, and a modulus of elasticity over 100 Pa, and even more preferably over 200 Pa. All the above rheological measurements were carried out using standard techniques, such as those described in the work of HA Barnes et al., Introduction to Rheology, Elsevier Publishing, Inc., 1989. Densities are usually from 850 to 970 kg / m3, preferably 890-970 kg / m3<sup>3</sup>. Molecular weight dispersions (Mw / Mn) are usually greater than 2.0, preferably 3.0-10.0. Typical melting points are from 50 to 13 ° C.
Preferred polymers additionally exhibit the properties of homogeneous polymers as defined in US Patent No. Amer. No. 3,645,992, i.e. copolymers of ethylene with substantially statistical comonomer distribution in a given molecule and with substantially the same ethylene / comonomer ratio in different molecules. Polymers produced at higher polymerization temperatures, especially at temperatures above 130 ° C, may exhibit a heterogeneous melt curve. The polymers of the invention are furthermore characterized by considerable transparency. In particular, polymers have better optical properties, especially less turbidity than typical ethylene polymers. That is why they are particularly well-suited for the production of films and injection products.
In addition, it has surprisingly been found that such olefin-containing polymers and an aromatic vinylidene polymer, especially ethylene and styrene, have elastomeric properties. Therefore, these polymers are uniquely suited for use in thermoplastic elastomer applications, such as impact strength modification of thermoplastic and thermoset polymers, including bitumens, adhesives, elastomeric moldings, etc.
Polymers prepared using the catalyst of the invention can be modified in a conventional manner by grafting, crosslinking, hydrogenation, introduction of functional groups or other reactions well known to those skilled in the art. Particularly with respect to polymers containing vinylidene, vinylcyclohexene or 1,4-hexadiene aromatic groups, sulfonation or chlorination can be easily carried out to obtain functional derivatives according to known techniques. Additional vinylcyclohexane based polymers can be easily crosslinked as a result of the unsaturated ring reaction.
These polymers, regardless of whether they have been further modified, can be mixed with synthetic or natural polymers to obtain blends with the desired properties. In particular, they can be mixed with polyethylene, ethylene / α-olefin copolymers, polypropylene, polystyrene, styrene / acrylonitrile copolymers (including their rubber-modified derivatives), syndiotactic polystyrene, polycarbonate, polyamide, aromatic polyester, polyisocyanate, polyurethane and polyoxyphenylene. The polymeric modifier is used in amounts of from 0.1 to 99.0, preferably 0.5-50% by weight.
Particularly preferred are polymers containing ethylene and styrene, which are elastomeric as defined in the definition of an elastomeric substance in ASTM Special Technical Bulletin No. 184 as a substance that can be stretched at room temperature to double its length, but will return to its original length after the release of voltage .
In addition to the use for the modification of synthetic thermoplastics, these polymers can also be successfully used as modifiers of asphalt or bituminous compositions. In this way, styrene-ethylene polymers are preferably used.

The term "bitumen can generally be defined as a mixture of hydrocarbons of natural or pyrolysis origin, or combined, often with the addition of their non-metallic derivatives, which may be gaseous, liquid, semi-solid or solid, and which usually dissolve in carbon disulphide. From the point of view of the invention, liquid, semi-solid or solid bitumen can be used. From a technical point of view, bitumen is essentially limited to asphalt, tar and pitch.

It is understood by specialists that the molecular weights of various bitumens can vary in a very wide range, e.g. from 500 to 10,000. Softening temperatures of various types of asphalt, e.g. from 10 to 200 ° C, can also vary.
Of the many types of bitumens that can be used, natural and petroleum bitumens are desirable, with petroleum bitumens being preferred. Of the petroleum bitumens, thermal bitumens are preferred.
Bitumen is used in the compositions of the invention in amounts in the range of 65 to 99% by weight, preferably in amounts of 80-98% by weight.
After describing the invention, the following examples are given to illustrate it in more detail without limiting its substance. Unless otherwise stated, all parts and percentages are by weight.
Example 1. Preparation of dichloride (tert-butylamido / dimethyl / tetramethyl-n-cyclopentadienyl) -anyl zirconium.

Polymerization
A. 5 ml of a 1 (00) M (molar) solution of methylaluminoxane (MAO) in toluene was added to a dosing container containing 25 ml of 4-methyl-1-pentene. The catalyst solution was prepared by adding 500 µl 0.01172 M CsMe solution<sub>4</sub>(Me 2 Si-N-t-Bu) ZrCl<sub>2</sub> in toluene to 2 ml of toluene in a second dispensing tank. Both tanks were closed, removed from the handling chamber and connected to a 600 ml stainless steel pressure tank. Air was removed from the pressure vessel and the vessel was purged with nitrogen.
A 4-methyl-1-pentene (toluene) MAO solution was added to the pressure vessel and heated to 89 ° C under 620 kPa ethylene with stirring. After adding the catalyst solution to the 4-methyl-1-pentene (toluene) MAO mixture, the ethylene pressure was increased to 12-40-1275 kPa. After 2 hours, the solution was cooled to 30 ° C and deaerated. The yield of polymer obtained after drying under reduced pressure at 100 ° C overnight was 10.0 g. Analysis of the polymer by the method<sup>13</sup>C NMR showed that it is a statistical copolymer of ethylene with 4-methyl-1-pentene.
B. Polymerization procedure A essentially - repeated, 50 ml - hexene instead of 4-methyl-1-pentene, and the catalyst concentration in toluene was 0.01012 M. The catalyst solution was added to the 1-hexene (MAO) ethylene mixture, followed by ethylene pressure increased to 1240-1275 kPa. After adding the catalyst solution, the temperature of the reaction mixture increased to 139 ° C. After 30 minutes, the solution was cooled to 100 ° C. Heating and ethylene feed were discontinued, after which the reactor was cooled and vented. The yield of polymer obtained after drying under reduced pressure at 100 ° C overnight was 36.8 g. Analysis of the polymer by the method<sup>13</sup>C NMR showed that it is a statistical copolymer of ethylene with 1-hexene (8 mol%).
C. The polymerization procedure A was essentially repeated, except that 213 l catalyst solution (0.001172 M in toluene) and 143 mg solid MAO were used. No additional olefin was introduced. After adding the catalyst solution to the reactor, the temperature increased to 109 ° C due to the exothermic polymerization reaction. The reaction was stopped after 1 hour by cooling and venting the reactor. The yield of polyethylene obtained after drying under reduced pressure at 100 ° C overnight was 11.0 g.
D. 150 ml of toluene was added to the pressure tank used in polymerization A, followed by 100 g of propylene. A solution of 0.828 g MAO in 8 ml toluene was added, followed by a 2130 μΐ catalyst solution. The reaction mixture was kept at 8 ° C for 3 hours. The reaction was quenched with acidified methanol to give 0.38 g of a white viscous material. Polymer analysis by the method<sup>n</sup>C NMR showed that it is atactic polypropylene.

Polymerization
Polymerization of the styrene / ethylene mixture was carried out by combining a 1.65 ml 10% MAO solution in toluene with a solution of 45 ml toluene and 50 ml styrene in a stainless steel dosing tank. 250fA 0.010 M dichloride solution (tert-buylamido / dimeiyic / tetramethylG-j ^^ cycpenidienyloyl titanate) was added to 2.5 mL toluene in a second dispensing tank. Both tanks were closed, removed from the handling chamber and connected to a 600 mL stainless steel pressure tank. Air was removed from the pressure vessel and then purged with argon.
The styrene / toluene / MAO solution was added to the pressure vessel and heated to 89 ° C under 620 kPa ethylene pressure with stirring. At this point, the catalyst solution was added and the pressure was increased to 1275 kPa, then maintaining it in the range of 1240-1275 kPa. As a result of the exothermic reaction, the temperature increased to 95 ° C. The temperature was lowered to 90 ° C and then kept in the range of 90-92 ° C in the further reaction.
After 1.0 hour, the ethylene supply was stopped. The reactor was vented and cooled to 30 ° C while adding methanol. The product was collected, washed with methanol and the remaining solvents removed under reduced pressure at 120 ° C to give 9.02 g of material. Analysis<sup>14</sup>The C NMR of this material showed that it was a styrene (15.2 mol%) statistical copolymer with ethylene, not containing polystyrene bound peaks.

The titanium catalyst and triethylaluminum as cocatalyst in solution were then added under pressure to a 3 dm SN pressure tank<sup>3</sup>, containing 2 dm<sup>3</sup> mixed alkane solvent (Isopar E available from Εχχοη Chemicals, Inc.) at 3100kPa ethylene pressure, at 150 ° C. The reaction temperature I50 ° C was maintained for -10 minutes. The ethylene pressure was kept constant. A mass flow meter showed that 15.7 g of ethylene had been absorbed. The polymer solution was removed from the pressure vessel. The polyethylene was isolated after drying overnight under reduced pressure at 90 ° C. Yield - 15.7 g.

In a handling chamber under an argon atmosphere, 5.0 ml of a 1.0 M solution of methylaluminoxane (MAO) in toluene was combined with 50 ml of 1-octene in a stainless steel (SN) dosing tank equipped with ball valves at both ends. In another metering tank with SN 500 // 1 (5.06 // mol) 0.0101 M dichloride solution (tert-butylamido / dimethyl / tetramethyl- / 7<sup>5</sup>-cyclopentadienyl) silane zirconium in toluene was mixed with 2 ml toluene.
The dosing tanks were closed, removed from the handling chamber and connected to a 600 ml SN pressure tank. The pressure vessel was pumped out of air and then purged with argon. A 1-octene solution and MAO were introduced into the pressure vessel. The solution was heated to 89 ° C under 620 kPa ethylene pressure with stirring. At this point, the catalyst solution was added. As a result of the exothermic reaction, the temperature increased to 142 ° C. The ethylene pressure was kept within the range of 1310-1345 kPa.
After 0.5 hours, the ethylene supply was discontinued. The reactor was cooled to 30 ° C, vented to atmosphere, and then quenched with methanol. The rest of the solvent was removed under reduced pressure at 110 ° C to give 35 g of material. Analysis<sup>f3</sup>C NMR showed that the 1-octene content of the polymer was 7.8 mol%. Differential calorimetry (DSC) showed a melting point of 100 ° C. Density 895 kg / m<sup>3</sup>, Mw 44,000; Mw / Mn = 6.8.
