Patent ID: 7300914

Claim:
A process for preparing a concentrate in liquid or liquid-disperse form, comprising I) from 5 to 80% by weight of a polymer obtainable by free-radically polymerizing acryloyldimethyltaurine, acryloyldimethyltaurates or mixtures thereof in the presence of one or more substances selected from one or more of the components D) to G), D) consisting of at least monofunctional silicon-containing substances capable of free-radical polymerization; E) consisting of at least monofunctional fluorine-containing substances capable of free-radical polymerization, F) consisting of olefinically mono- or polyunsaturated, optionally crosslinking macromonomers which each have at least one oxygen, nitrogen, sulfur or phosphorus atom and a number-average molecular weight greater than or equal to 200 g/mol, the macromonomers not being silicon-containing substances as per component D) or fluorine-containing substances as per component E), and G) consisting of polymeric additives having number-average molecular weights of from 200 g/mol to 10 9 g/mol, II) from 20 to 95% by weight of an organic solvent or solvent mixture, III) from 0 to 60% by weight of an emulsflier, and IV) from 0 to 30% by weight of water, comprising the steps of: a) polymerizing acryloyldimethyltaurine, acryloyldimethyltaurates or mixtures thereof in the presence of at least one substance or a plurality of substances selected from one or more of the components D) to G) by a free-racical polymerization reaction in a polymerization medium which behaves inertly with respect to free-radical polymerization reactions and permits the formation of high molecular weights, b) subsequently adding a higher-boiling solvent or solvent mixture, to the mixture of polymer and polymerization medium obtained from step a), the boiling point of the higher-boiling solvent or solvent mixture added being at least 10° C. higher than that of the polymerization medium used for the polymerization, and c) subsequently removing the polymerization medium.
