摘要：
The invention relates to water-soluble or water-swellable polymers that contain a) 20.0 to 98.97 mole-% of one or more repeating structural units originating from special monomers with sulfonic acid groups or the salts thereof such as e.g. 2-acrylamido-2-methyl-propanesulfonic acid or the salts thereof, b) 1.0 to 60.0 mole-% of one or more repeating structural units containing an amide group and d) 0.01 to 8.0 mole-% of one or more repeating structural units originating from special crosslinking agents with at least three polymerizable double bonds. The polymers for example have an advantageous sensory property profile and are highly suitable as thickening agents even in salt-containing compositions. They are furthermore advantageously suitable for producing cosmetic, dermatological or pharmaceutical compositions.
