Fund Project: This work was financially supported by the National High Technology Research and Development Program of China (No.2007AA03Z532), the National Natural Science Foundation of China (No.20774015), and the China National Petroleum Corporation Innovation Fund (No.07E1034).

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.
