Abstract (en)
[origin: EP0368214A2] The use of copolymers which contain as essential copolymerised units (a) 50 to 99 mol% of units of monoethylenically unsaturated (a) C3- to C8-monocarboxylic acids, monoethylenically unsaturated C4- to C8-dicarboxylic acids, hemiesters of monoethylenically unsaturated C4- to C8-dicarboxylic acids, esters of monoethylenically unsaturated C3- to C8-carboxylic acids, C2- to C30-olefins, styrene, C1- to C3-alkylstyrenes, C1- to C28-alkyl vinyl ethers, vinyl esters of saturated C1- to C8- carboxylic acids or mixtures of units of these monomers and (b) 50 to 1 mol% of units of amides of monoethylenically unsaturated C3- to C8-carboxylic acids with amide groups of the structure <IMAGE> in which R<1> = C8- to C28- alkyl, <IMAGE> R<3>, R<4> = H, CH3, C2H5 R = C1- to C28-alkyl, n = 2 to 100 and R<2> = H, R<1> have K values of 8 to 200, or of salts of these copolymers, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and aqueous liquid detergent compositions which contain these copolymers.
