Abstract:
A water-soluble or water-swellable copolymer obtained by free-radical copolymerization ofA) acryloyldimethyltaurine and/or acryloyldimethyltaurates, B) optionally, one or more other olefinically unsaturated, optionally crosslinking, comonomers containing at least one oxygen, nitrogen, sulfur or phosphorus atom and possessing a molecular weight of less than 500 g/mol, and C) one or more at least monofunctional, fluorine-containing components capable of free-radical polymerization, at least one fluorine-containing component being a compound of the formula (I) R1â€”Yâ€”CrH2rCsF2SCF3â€ƒâ€ƒ(I) â€ƒwhere R1 is an acryloyl or methacryloyl radical; Y is a chemical bridge, and r and s are stoichiometric coefficients which independently of one another can be numbers between 0 and 200, and with the copolymerization taking place D) optionally in the presence or absence of at least one polymeric additive having number-average molecular weight of from 200 g/mol to 109 g/mol.
