Abstract

The invention relates to compositions comprising copolymers based on acryloyldimethyltaurine and also synergistic additives selected from anionic, cationic, nonionic, and betaine surfactants. The compositions exhibit a pronounced thermoassociative behavior and are outstandingly suitable as thickeners. The copolymers of the present invention are useful in formulating cosmetics, pharmaceuticals, and oil field chemicals.
