| 摘要 |
The invention relates to an aqueous dispersion of a copolymer incorporating by polymerization units of a) at least one ethylene unsaturated carbonic acid, b) at least one non-ionic ethylene unsaturated tenside monomer, c) at least one C-C-alkylmethacrylate, d) at least one C-C-alkylacrylate, the alkyl chain length averaged over the number of alkyl groups of the alkylacrylate being 2.1 to 4.0. After neutralization using alkali, the dispersion serves as an associative thickener, particularly for liquid washing and cleaning agent formulations. The thickeners are characterized by high transparency and high thickening effectiveness at simultaneously high shear dilution.
