Abstract
This invention relates to organopolysiloxane-modified graft copolymers obtained by a method comprising heating a mixture comprising an ethylenically unsaturated monomer, a polyethylene-polybutylene macromonomer, an organopolysiloxane macromonomer, a free radical initiator, and optionally a solvent. The copolymers of this invention find utility in adhesives such as pressure sensitive adhesives, contact adhesives. laminating adhesives, and assembly adhesives, and release coatings.
