Abstract: The present invention relates to copolymers prepared by copolymerization in at least two stages, wherein, in one stage (A) at least one (co)polymer is prepared from a monomer or a mixture of comonomers comprising (a1) from 80 to 100% by weight of at least one ethylenically unsaturated carboxylic acid, (a2) from 0 to 20% by weight of at least one C 1 -C 22 -alkyl ester of at least one ethylenically unsaturated carboxylic acid, (a3) from 0 to 10% by weight of at least one further ethylenically unsaturated compound, data in % by weight being based on the total amount of comonomers of the relevant stage, and the (co)polymer thus obtained is reacted in a subsequent stage (B) with a further comonomer or a further mixture of comonomers comprising (b1) from 0 to 30% by weight of at least one ethylenically unsaturated carboxylic acid, (b2) from 70 to 100% by weight of at least one C 1 -C 22 -alkyl ester of at least one ethylenically unsaturated carboxylic acid, (b3) from 0 to 10% by weight of at least one further ethylenically unsaturated compound, data in % by weight being based on the total amount of comonomers of the relevant further stage.

Abstract: A process for preparing copolymers which comprises copolymerizing (A) at least one ethylenically unsaturated dicarboxylic anhydride derived from at least one dicarboxylic acid having 4 to 8 carbon atoms, (B) at least one vinylaromatic compound, and (C) optionally at least one non-(A) ethylenically unsaturated comonomer containing at least one heteroatom, (D) reacting the copolymer with at least one compound of the formula I a or I b where A 1 is C 2 -C 20 alkylene, identical or different, R 1 is C 1 -C 30 alkyl, linear or branched, and n is an integer from 1 to 200, hydrolyzing the product with water or an aqueous alkaline solution, and subsequent to hydrolysis adding further free-radical initiator.

Abstract: A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
