ABSTRACT:
The invention describes novel silicone-containing graft copolymers and processes for their preparation. In particular, it relates to silicone-containing graft copolymers P, which are obtained by grafting olefinic monomers M onto polyether-containing radicals of polyoxyalkylene-polysiloxane block copolymers S with (AB)nstructure.
