POLYMERS BASED ON SULFONIC ACIDS, AMIDES AND SPECIAL CROSS-LINKING AGENTS

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 cross-linking 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.
