Usaturated quaternary monomers and polymers
Abstract
This invention is concerned with monoethylenically unsaturated acid ester monomers, such as those of acrylic or methacrylic acid, containing a quaternary ammonium halide group having a substituent on the quaternary nitrogen atom of the formula -CH2CH(OH)CH2X wherein X is chlorine, bromine or iodine. It is also concerned with addition polymers of such monomers, and methods of producing the monomers and polymers. The monomers and polymers are stable at acid pH values, although capable of reacting with other reactants for the hydroxyl and/or halide group. At alkaline pH values, they become self-reactive and the polymers crosslink themselves by slow reaction at room temperature. However, the reaction becomes quite rapid on heating.

In the isers of formula I, R and R are preferably both methyl, and A is a (C 1 -C 6 alkylene group, or a polyoxyethylene group of the formula (CH 2 CH 2 O 2 CH 2 Cl 2 wherein x is at least 1, Y may be halo)<sup>-</sup>.

Polymers are stable at acidic pH values, although they are capable of reacting with other reagents that react with the hydroxyl and / or halide group. At alkaline pH values, they become self-reactive, and the polymer itself forms crosslinks by a slow reaction at room temperature. However, upon heating, the reaction becomes quite rapid.

The salts used as starting material and epihalohydrin are so highly soluble in water that water is perfectly suitable as a reaction medium. Epihalohydrin is preferably used in either a stoichiometric amount or more. The aqueous medium may contain a water-miscible co-solvent when A is an alkylene group having four or more carbon atoms. No catalyst is required for the reactions. However, it is essential that the pH be maintained on the acidic side during the reaction to prevent adverse side reactions. React is rapid even when started at room temperature. Its termination can be easily determined by monitoring the decrease in amine titer as the amine group quaternizes. The addition of epihalohydrin to the aqueous starting salt solution is generally performed as rapidly as the sketch state control of the reaction system allows.
The reaction medium may contain some polymerization inhibitor. Examples are e.g. hydroquinone monomethylethyl ether, hydroquinone and phenothiazines. The amount of inhibitor can range from 0.01-1 # by weight of the starting salt.
The carbon atoms of group A of formula I may be in either a single straight chain or a branched chain. However, at least one hydrogen must preferably be attached to the carbon atom of the group A directly attached to the nitrogen atom so that the reaction is not sterically hindered.
The epihalohydrin may be epiodihydrin or epibromohydrin, but is preferably epichlorohydrin. Similarly, the salt of the polymer may be any of the hydrochloric acid salts, e.g. hydroiodide or hydrobromide, but is preferably hydrochloride. Typ ..... .1.2.
although the substituents R and R associated with the atom may be cyclohexyl or any alkyl group having no more than 6 carbon atoms, the compounds of formula I in which both of these groups are hydrogen groups do not suggest that dimethyl compounds are most suitable in practice.
Aqueous solutions of quaternary monomers can be used to prepare the polymer of the invention. Any known free radical type polymerization initiator can be used here. Examples are e.g. t-butyl hydroperoxide, ammonium persulfate and alkali metal persulfate, cuten sodium potassium persulfate. They are used in a conventional amount of 0.1 to 2% by weight of the monomer. They can be used with sodium hydrosulfites or other reducing agents in a redox system. Alternatively, the polymerization can be accomplished by irradiation.
These quaternary ammonium salt monomers can be copolymerized with other polymerizable, ethylenically unsaturated monomers, in particular by emulsion polymerization processes, in which case, if desired, counterpartizers can be used as initiators. As emulsifiers, t-octyl or t-nonyl-phenoxypolyethoxy-ethanol oil having n. 10-50 to one of the oxyethylene dimers, octadecylylaminosulphate, cyclohexyl-diethyl (dodecyl) -aminisulphate, octadecylitrimethylammonium bromide, polyethoxyamines, polyacetylene to the same.
Any ethylenically unsaturated monomer having a group Η<sub>2</sub>Ο = Οζ ^, can be used for copolymerization with the new monomers of the formula I under conditions such that the polymerization medium remains acidic, preferably at a pH of not more than 6. Examples<sub>2</sub>C = C group, are e.g. acryylhapone and methacryylihapone esterite (C -ethylhexylylacrylate and methacrylate, octadecylacrylate and methacrylate, vinyl aromatic acetate (ethylene, styrene, isopropenyl) -toluene and dialylacylated styrene); acrylonitrile, methacrylonitrile, ethacrylonitrile and phenylyl acrylonitrile; acryyliamide, methacryyliamide, ethacryyliamide, N-methyloliacryyliamide, N-monoalkyyli- and -dialkyyliacryyriamidite and -methacryyliamidite, esim.

N-monophenyyl- and diphenyyl-acryyliamidite and -methacryyliamidite; B-hydroxyethyl acrylate and methacrylate.
The monomers of formula I are directly useful for copolymerization with acrylonitrile to modify their electrical charge, dyeing absorption properties. The resulting copolymer containing 0.2-5% by weight of a quaternary ammonium compound of the present invention can be formed into fibers from which textile yarns can be made. moisture adsorption or recovery is increased. Then, instead of copolymerizing the monomer of the invention as such with acrylonitrile to form the major component of fibers or films, one homopolymer or copolymer of monomer of formula In the main component of the fiber or film then made from the mixture.
The polymer of the invention can be used for sizing paper and can be prepared in situ. A small amount, 0.2-5 1% by weight of the quaternary monomer, based on the dry weight of the fibrous material, can be mixed into the pulp in the cholester or just before or immediately after the pulp leaves the cholester. A polymerization initiator may be added to the pulp at the same time as, or shortly after, the monomer of formula I. The effect thus obtained on dry paper varies depending on the pH of the system. If the pH of the pulp is below 7, a gluing effect is obtained on the paper. The mass is neutral to alkali, to alkaline alkali, and to pH. 8-10 at some point before the formed paper is dried, the wet strength is also improved.
An aqueous dispersion of neutral or acid-containing polymer (such as poly (ethylyacrylate) obtained by emulsion polymerization can also be added to the pulp. In this case, the quaternary polymer is used to anchor the additional polymer to the fibers. Instead of this additional polymer, an aqueous dispersion of a wax such as polyethylene, a pigment or mineral filler, or a substance such as a long-chain alcohol-modified urea formaldehyde resin can be added, which kale the paper.
Alternatively, the polymers of the invention may be prepared by reacting an epihalohydrin with a polymer containing 0.25 to 100% by weight of an amine salt of the above formula ITT. This polymer can be obtained by polymerizing an amine salt of formula III directly, or by polymerizing the corresponding amine in the form of a free base and then neutralizing it with a hydrogen acid to form a salt of the amine polymer. Numerous methods for polymerizing amine salts of formula III and corresponding free base amines (wherein copolymerization is included within the scope of this term) are known in the art, and any of these methods. Conventional emulsion or suspension polymerization methods can be used. Any of the comonomers listed above as suitable for copolymerization with a quaternary ammonium compound of formula I may also be used as comonomers in the form of amine salts of formula III or the like free base ood.
The epihalohydrin and the polymeric isoelectric reaction can be carried out in the same manner and under the same conditions as the reaction between the monomer of formula III and the epihalohydrin. The polymer may be dissolved in water, or it may be in the form of an aqueous latex obtained by emulsion polymerization. Epihalohydrin is used in stoichiometric equivalence to convert the desired amount of amine units in the polymer to quaternary ammonium units, or a small excess (Up to 25%) of a copolymer of ammonium salt can be used.

R<sup>2</sup> The relative amounts of IV and V vary depending on the exact reaction conditions, but are typically approximately equivalent amounts. Lowering the pH seems to reduce the proportion of V. At pH values of 6 or less, the tendency to gel due to the glycidyl group of V is inhibited, while from raising the pH to neutral or temporal conditions
57767 rapid curing of the copolymer occurs even at room temperature, in an insoluble state, and the higher the pH and concentration of the polymer, the faster the curing. Sample IV groups become V groups when the pH is made alkaline, and alkali-catalyzed changes in glycidyl groups can cause the polymer to cure and become insoluble.
However, if the polymers of the invention containing groups IV are diluted into very dilute (2-10 #) aqueous solutions at 550 ° C, the pH can be raised to 9-12 without gelling. The polymer thus obtained is stable for a relatively short time when diluted (2-10 #), although this polymer polymer cannot be stored indefinitely without gelling or losing its functionality. The polymers of the invention activated by such an alkali treatment lasting 1 to 5 hours or more have been found to be two to three times more effective as wet strength resins than before activation. This alkali activation process is of particular importance because the polymers treated in this way are particularly valuable as wet strength resins for paper when the paper is tempered at pH 6-10. It is possible to use an alkali activation process not suitable for use in a polymer factory for use by a polymer manufacturer, due to the previously mentioned stability problems and the required dilution (2-10 #), it may be suitable for the polymer user.
These properties of Group IV and possibly some Group V polymers allow the polymer manufacturer to produce reasonably stable polymer blends such as their latices, as well as to preserve paper at pH 2-5 for simple sizing, or at pH 7-11 or above. for curing an existing polymer to develop good wet strength.
Homopolymers of a compound of formula I or copolymers containing both groups IV and V are generally water soluble up to at least 1% by weight at room temperature, and in most cases are soluble in aqueous solutions, as well as a number of years.
The homopolymer is the now widely used group of cells, the wood and the vesicle suspension selected. Thus, by adding to the effluent about 0.01 to 0.5% by weight, based on the weight of the suspended solid, of the homopolymer of the monomer of formula I, the suspended matter is flocculated so that it can be easily removed from the mouth. Homopolymers can thus be used in many types of aqueous suspensions
57767 flocculation, in particular for the flocculation of domestic and industrial effluents of a neutral, acidic or alkaline nature. As previously mentioned, they can be used as sizing and wet strength agents for paper and as sizing agents for other sizing agents used in aqueous dispersions or suspensions. This is a non-profit organization that has a limited number of paperwork options, and it is not possible to obtain a copy of any of these articles. The sizing and flocculation performance is generally obtained at all pH values of the systems in which they are used.
Treatment of the pulp with homopolymers (especially after alkali activation) under neutral or temporal conditions and subsequent cholester grinding significantly improves the wet strength. The amount of polymer used for this purpose may vary from 0.5 to 7 or more by weight, based on the dry weight of the fibrous material in the pulp, whereby the wet strength improves with increasing dosage. Up to 4-5 #, after which the wet strength no longer increases and the gluing effect increases.
Water-soluble copolymers containing 25% or more of units of formula IV, whether or not they also contain units of formula V, as well as those copolymers whose units consist of a monomeric homopolymer of the same yield. The paper does not contain the resin which is copied and copied with a small amount of n. 35-100 # units of formula IV and units of formula V, and for best performance, these resins are subjected to an alkali activation process at a concentration of 2-10 # just prior to use.
The copolymer, which contains 0.25 to 25 weight # or more units of Formula IV, is useful for many purposes. For example, copolymers of acrylonitrile with 0.25-15 # units of formula IV are particularly useful in the manufacture of fibers and films with improved dyeability, higher resistance to electric chain goat elastic. Copolymer with approx. 0.5-30% of the only IV monomeric monomer Acrylic acid in the methacrylic acid ionic ester, ethylene acrylate, butyl acrylate, 2-ethylhexyl Acrylic acrylate and methylimethacrylic acid are used in the vinyl resin, woven textile binding, leather finishing, pigmented mixtures binders, pigment dyeing of textiles, For the production of mineral-coated papers and lithographic inks, for gluing paper and as thermosetting coatings for metals, wood, plastics, glass, all types of masonry, plastered walls, etc.
