| abstract |
The invention provides stable dispersion concentrates comprising:n I) 5 to 80% by weight, preferably 10 to 80% by weight, particularly preferably 20 to 60% by weight, especially preferably 30 to 40% by weight, of a polymer which, in random distribution, consists of 90 to 99.99% by weight of monomers of the formula (1)n nH 2 C═CHCONHC(CH 3 ) 2 CH 2 SO 3 X (1)n and 0.01 to 10% by weight of crosslinking structures originating from monomers with at least two olefinic double bonds, where X is a cation or a mixture of cations, and X must consist of not more than 10 mol % of protons, II) 20 to 95% by weight of one or more emulsifiers and/or an oil phase, and III) 0 to 30% by weight of water. |
