摘要
The invention relates to copolymers which can be obtained by radical polymerisation of (A) at least one monoethylenically unsaturated C4-C8 dicarboxylic acid anhydride, (B) at least one vinylaromatic compound from the group containing styrol and substituted styrols, and (C) at least one monoethylenically unsaturated monomer which contains at least one heteroatom and is different from (A); by partial esterification of the obtained copolymers with (D) alcohol alkoxylates of formula (I) wherein the variables have the following designations: R represents C2-C6 alkylene radicals which can be the same or different for n1, RSUP1 /SUPrepresents C 1 -C 30 alkyl, and n represents a number between 1 and 200; and as desired, by hydrolysis of the anhydride groups still contained in the copolymers in order to form carboxyl groups. The invention also relates to the use of said copolymers as additives for washing and cleaning products.
