Abstract (en)
[origin: WO0244268A1] The invention relates to water-soluble or water-swellable copolymers, which can be obtained by radically copolymerizing: A) acryloyldimethyl taurine acid and/or acryloyldimethyltaurates; B) optionally one or more additional olefinically unsaturated, optionally cross-linking comonomers, which comprise at least one oxygen atom, nitrogen atom, sulfur atom or phosphorous atom and which have a molecular weight of less than 500 g/mol; C) one or more macromonomers, which are olefinically unsaturated once or a number of times, which are optionally cross-linking, which each comprise at least one oxygen atom, nitrogen atom, sulfur atom or phosphorous atom, and which have an average molecular weight of greater than or equal to 200 g/mol, whereby the copolymerization; D) ensues in the presence of at least one polymeric additive having an average molecular weight ranging from 200 g/mol to 10<9> g/mol.
