Abstract

A polymerization process characterized in that it comprises copolymerizing with ethylenically unsaturated monomer a monomer emulsion stabilizer of the formula **(See formula)** wherein V is an ethylenically unsaturated radical selected from the following classes: a) ester-acid groups or amido-acid groups represented by the formulas HO-CO-CH = CH-COO-, HO-CO-CH = CH-CONH-, HO-CO-CH = C (CH3) -COO-, HO-CO-CH = C (CH3) -CONH-, (see formula); b) acrylic ester or acrylic amide groups represented by the formulas CH2 = CR4-COO- and CH2 = CR4-CONH, with R4 H or CH3; c) allyl, methallyl, vinyloxy, allyloxy, methyloxy, vinyl acetoxy, allyl acetoxy, or metalyl-acetoxy; A is absent when V is an allyl, metalyl, vinyl acetoxy, allyl acetoxy, or metalyl acetoxy group and is otherwise a group selected from the classes consisting of ethylene, propylene, hydroxypropylene, acetoxy, propylene, ixopropylene groups, and -O -CH2-CHR4- (O-CH2-CHR4) n-, where R4 is H or CH3 and where n is 0, 1, 2, 3 or 4; the quaternary nitrogen group N + .R1.R2.R3 is selected from the classes consisting of: a) aliphatic tertiary amines in which R1 is an alcoholic or benzyl group containing 1 to 7 carbon atoms, and R2 is a group alcohol or benzyl containing 1 to 7 carbon atoms or a group selected from the class consisting of R5-O-CO-CH2- and R5-NH-CO-CH2, -, where R5 H or an alcohol group containing from 1 to 4 carbon atoms; b) groups in which n, R1 and R2 together form part of a heterocyclic tertiary amine having the formula **(See formula)** and R3 is a lipophilic radical containing an aliphatic hydrocarbon chain of 7 to 28 carbon atoms; and X- is a radical selected from (a) the class consisting of F-, Cl-, Br-, I-, CH3SO4, C2HSO4-, CH3- or SO3-, or (b) an alcoholic sulfate in which the group alcohol contains 7 to 28 carbon atoms, an alcohol benzene sulphonate in which the alcohol group contains 7 to 12 carbon atoms, a phenoxy (or alcohol phenoxy) alcohol (or polyalcohilenoxi-alcoholilen) sulfate that has the formula R'' - C6H4O- (CH2-CHR'''- O) n-CH2-CHR''' SO4 where R'' is hydrogen or an alcohol group containing 1 to 12 carbon atoms, where R'''is hydrogen or a methyl group, and where n is zero or an integer; a dialkoxy sulphosuccinate in which the alcoholic groups contain 1 to 24 carbon atoms or an alcoholic phosphate in which the alcoholic group contains 1 to 18 carbon atoms, with the proviso that when X- falls within class (b), R3 It is a lipophilic radical that contains a hydrocarbon chain of 8 to 28 carbon atoms.
