Graft copolymers containing perfluoroalkyl groups

Aq. dispersions of copolymers and/or graft copolymers from (a) ethylenically unsatd. perfluoroalkyl monomers and (b) ethylenically unsatd. monomers free from perfluoroalkyl gps., are prepd. by polymerisation in presence of aq., emulsifier-free polyurethane dispersions as graft backbone, based on (c)...
