Abstract
The invention relates to copolymers which contain a) at least 15% by weight units of an ethylenically unsaturated carboxylic acid, b) at least 15% by weight units of a C-C-alkylacrylats, c) less than 5% by weight units of methyl methacrylate, and are used as thickeners in liquid textile detergents. The copolymers can additionally contain units of a non-ionic ethylenically unsaturated surfactant monomer that are incorporated by polymerization. The thickeners are characterized by high thickening action, high shear thinning and low graying of the laundry after the washing process.
