Graft copolymerization process |
摘要 |
Novel graft copolymers of isobutylene-conjugated diene copolymeric backbones are prepared employing polymer lithiation wherein the polymeric lithiated complex is treated with an ether compound prior to a graft copolymerization reaction with styrene monomer whereby improved grafting efficiencies are obtained.
