a) One or more repeating structural units of the following formula (1) [R 1 represents hydrogen, methyl or ethyl, and A represents C 1 -C 8 -alkylene, and Q + represents H + , NH 4 + , Li + , Na + , K + , 1 / 2Ca ++, 1 / 2Mg ++, represents 1 / 2Zn ++ or 1 / 3Al +++, and the degree of neutralization of the structural units of the formula (1) is 50 to 100 mol% And b) one or more repeating structural units of the formula (2) [R 1 and A have the meanings of R 1 and A in formula (1) and X + represents [HNR 5 R 6 R 7 ] + , where R 5 , R 6 and R 7 are Independently of each other, hydrogen, linear or branched alkyl group having 1 to 22 carbon atoms, linear or branched mono- or polyunsaturated alkenyl group having 2 to 22 carbon atoms, C 6 -C 22 -alkylamidopropyl group, linear mono-hydroxyalkyl group having 2 to 10 carbon atoms, or linear or branched di-hydroxyalkyl group having 3 to 10 carbon atoms, At least one of the R 5 , R 6 and R 7 groups is not hydrogen, provided that Q + represents NH 4 + , Li + , Na + , K + , Ca ++ , Mg ++ , Zn ++ or Al ++++ . Meaning structural unit of formula (1) and formula (2 The molar ratio of the structural units of 97: 3 to 55: A 45, and the corresponding alkyl chloride XCl has a critical micelle formation concentration <15 g / L (the critical micelle concentration) And c) crosslinkable structural units derived from monomers having at least two olefinic double bonds 0 to 8, preferably 0.01 to 5% by weight, A polymer comprising is disclosed. The polymers are advantageously suitable as thickeners, for example in cosmetic, dermatological and pharmaceutical compositions. |
