ABSTRACT:
The invention provides stable dispersion concentrates comprising: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)in-line-formulae description="In-line Formulae" end="lead"?H2C═CHCONHC(CH3)2CH2SO3X  (1)in-line-formulae description="In-line Formulae" end="tail"? 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, andIII) 0 to 30% by weight of water.
