摘　　要：A novel star-comb styrene/butadiene copolymer（SC-SBC） was synthesized by anionic polymerization and grafting reaction with epoxidized star liquid polybutadiene（ESPB） as coupling agent.The overall shape of the star-comb macromolecules can be altered by changing the molecular weight and number of the side chain.The molecular parameters and mechanical properties of the SC-SBC resins were investigated.The notched izod impact strength of the SC-SBC resins are excellent and reach as high as to 239 J/m.A novel star-comb styrene/butadiene copolymer（SC-SBC） was synthesized by anionic polymerization and grafting reaction with epoxidized star liquid polybutadiene（ESPB） as coupling agent.The overall shape of the star-comb macromolecules can be altered by changing the molecular weight and number of the side chain.The molecular parameters and mechanical properties of the SC-SBC resins were investigated.The notched izod impact strength of the SC-SBC resins are excellent and reach as high as to 239 J/m.
