    Abstract: A copolymer obtainable by free-radical polymerization ofA) 50-99.99% by weight of an olefinically unsaturated C3-C5 monocarboxylic acid, of an olefinically unsaturated C4-C8 dicarboxylic acid or the anhydride thereof or a mixture of such carboxylic acids or anhydrides withB) 0.01-50% by weight of an olefinically unsaturated quaternary ammonium compound of the formula I or II whereR1 is C6-C20-alkyl, C6-C20-alkenyl, C5-C8-cycloalkyl, phenyl, phenyl(C1-C12-alkyl) or (C1-C12-alkyl)phenyl,R2 is hydrogen, methyl or phenyl,R3 and R4 are each H or C1-C4-alkyl,X is halogen, C1-C4-alkoxysulfonyloxy or C1-C4-alkanesulfonate, it also being possible for the latter to occur as R3 or R4 with the formation of a betaine structure,Y is O or NH, andA is C1-C6-alkylene, or a mixture of such ammonium compounds,C) 0 to 49.99% by weight of an acrylate or methacrylate of the formula III where R1, R2 and Y have the abovementioned meanings, R5 is hydrogen, methyl or ethyl, and n is a number from 0 to 25,D) 0-49.99% by weight of other copolymerizable monomers andE) 0-5% by weight of one or more compounds with at least two olefinically unsaturated groups in the molecule as crosslinker. The copolymers are suitable as thickeners and dispersants, especially in cosmetic compositions.
