Aqueous dispersions of copolymers and / or graft copolymers from ethylenically unsaturated perfluoroalkyl monomers and perfluoroalkyl group-free ethylenically unsaturated monomers can be prepared by polymerization in the presence of aqueous, emulsifier-free polyurethane dispersions as a graft base based on compounds containing perfluoroalkyl groups with active hydrogen atoms and ionic compounds containing ionic and / or groups containing ionic and / or ionic and / or groups containing ionic and / or ionic and / or ionic and / or ionic compounds containing ionic and / or active compounds as well as polyisocyanates and can be used for the oleophobic and hydrophobic finishing of textiles, carpets, leather and paper. |
