The present invention relates to a process for producing water soluble or water swellable polymers containing acryloyl dimethyltaurate, neutral monomers and carboxylate group monomers. The monomers are polymerized by radicals in precipitation in a polar solvent or a mixture of solvents, provided that when the polar solvent contains 2-methyl-2-propanol, a ketone or both, another solvent must be contained. polar organic. |
