Date Jun. 29, 1995The present invention relates to copolymerizates (A) of unsaturated carboxylic acids, selected from carboxylic acids containing sulfonic acid groups, comonomer mixtures of carboxylic acids containing sulfonic acid groups with dicarboxylic acids, and comonomer mixtures of carboxylic acids containing sulfonic acid groups and/or dicarboxylic acids and their anhydrides, with other unsaturated compounds, in particular monoethylenically unsaturated monocarboxylic acids containing from 3 to 10 carbon atoms. Another embodiment of the invention comprises a process for the preparation of said copolymerizates (A), a mixture of copolymerizates (A) with analogous copolymerizates (B), as well as the use of the above copolymerizates and their mixtures as sequestering agents, complexing agents and co-builders in detergent and cleaning agent industry and as textile treatment aids. |
