WATER-SOLUBLE OR WATER-SWELLABLE POLYMERS ON THE BASIS OF SALTS OF ACRYLOYLDIMETHYLTAURINE ACID OR THE DERIVATIVES THEREOF, THE PRODUCTION THEREOF AND THE USE THEREOF AS THICKENER, STABILIZER AND CONSISTENCY AGENTS

摘要

New polymers comprise ammonium or metal N-sulfoalkylacrylamide units (I), organoammonium N-sulfoalkylacrylamide units (II) and 0-8 wt.% crosslinking units derived from monomers with at least two olefinic double bonds. New polymers comprise ammonium or metal N-sulfoalkylacrylamide units of formula (I), organoammonium N-sulfoalkylacrylamide units of formula (II) and 0-8 wt.% crosslinking units derived from monomers with at least two olefinic double bonds. CH 2-CHR 1-CONHASO 3Q (I) CH 2-CHR 1-CONHASO 3X (II) R 1H, Me or Et; A : 1-8C alkylene; Q : H (0-50 mole%) and M (50-100 mole%); M : NH 4, Li, Na, K, Ca, Mg, Zn or Al; X : HNR 5R 6R 7; R 5-R 7H, 1-22C alkyl, 2-22C alkenyl, 6-22C alkylamidopropyl, 2-10C hydroxyalkyl or 3-10C dihydroxyalkyl, but no all H, such that XCl has a critical micelle concentration of less than 15 g/l. The molar ratio of (I:Q=M) to (II) is 97:3 to 55:45. Independent claims are also included for: (1) producing the polymers by dissolving or dispersing the sulfonic acid CH 2=CHR 1-CONHASO 3H in an erotic solvent, neutralizing the sulfonic acid with a M-containing base and an amine XH, optionally adding a crosslinker, and adding a radical initiator; (2) cosmetic, pharmaceutical or dermatological compositions containing the polymers.
