The present invention relates to aqueous dispersions of graft polymers or graft copolymers containing as the graft base an aqueous polyurethane dispersion optionally containing block polyisocyanates in dispersed form as crosslinker and, as the graft covering, a polymer or a copolymer of ethylenically unsaturated monomers, characterized in that the graft covering is a polymer of ethylenically unsaturated perfluoroalkyl monomers having a molecular weight above 367 or a copolymer of perfluoroalkyl monomers such as these with comonomers free from perfluoroalkyl groups. The present invention also relates to a process for producing these dispersions and to their use as hydrophobizing and oleophobizing agents for textiles.
