SILICON-MODIFIED COMB POLYMERS BASED ON ACRYLOYLDIMETHYL TAURINE ACID (2-ACRYLAMIDO-2-METHYL-1-PROPANESULFONIC ACID)

摘要

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 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 at least monofunctional silicon-containing constituents, which are capable of radical polymerization, whereby the copolymerization; D) optionally ensues in the presence of at least one polymeric additive having average molecular weights ranging from 200 g/mol to 109 g/mol.
