This invention relates to graft copolymers containing polydiorganosiloxane and polybutylene grafts. More particularly this invention relates to a graft copolymer having a backbone and two or more polymeric side chains, the copolymer formed from the copolymerization of at least one acryloxyalkyl-functional polydiorganosiloxane macromonomer, at least one acryl-terminated, carboxyl-functional polybutylene macromonomer, and at least one ethylenically unsaturated monomer which is copolymerizable with the polydiorganosiloxane and polybutylene macromonomers. This invention also relates to a method of making graft copolymers containing polydiorganosiloxane and polybutylene grafts.
