ABSTRACT:
The present invention relates to graft copolymers based on at least one ethylenically unsaturated monomer containing perfluoroalkyl groups mixed with an acrylic, methacrylic, vinyl, maleic and/or styrene derivative and a melamine polycondensate as the graft substrate, which are suitable for oleophobic treatment of textiles, carpets, paper or leather and at the same time are effective hydrophobicity agents, and a process for their preparation.
