Abstract
Low-viscosity, water-soluble polymeric aqueous dispersions with high active substance concentrations containing a polymer (A), made up of water-soluble monomers (a1) and, optionally, amphoteric monomers (a2), as well as a polymeric dispersion agent (D) may be prepared by removing water during the polymerization of the polymer (A), in the presence of the polymeric dispersion agent (D) to afford the polymeric dispersion (PD'). In another embodiment, the process involves the addition of the polymeric dispersion agent (D) in aqueous solution to the polymeric dispersion (PD') in a second process stage, which leads to the polymeric dispersion (PD").
