摘要：
Copolymers, their use as thickeners, and methods for their preparation The present invention relates to copolymers comprising as comonomers in copolymerized form (A) at least one ethylenically unsaturated mono- or dicarboxylic acid, (B) at least one ethylenically unsaturated compound which has at least one structural unit of the general formula (I) per molecule: where the variables are defined as follows: R1 is different or identical and selected from hydrogen, C1-C30-alkyl, C6-C30-aryl and C7-C30-aralkyl, A1 is different or identical and selected from C2-C10-alkylene, C6-C10-arylene and C7-C10-aralkylene, n is different or identical and selected from zero to 200, m is different or identical and selected from 1 to 6, (C) at least one further comonomer.
