ABSTRACT:
Aqueous dispersions of copolymers and graft copolymers of ethylenically unsaturated perfluoroalkyl monomers having at least 6 C atoms in the perfluorinated chain and ethylenically unsaturated monomers containing no perfluoroalkyl groups, which additionally contain certain ester compounds which cannot be used as comonomers, are outstandingly suitable for finishing textile materials, leather and the like. Excellent oleophobic and hydrophobic effects are obtained.
