摘要：

A novel star-comb polybutadiene（SC-PB） was synthesized with n-butyllithium（n-BuLi） as initiator,epoxidized star liquid polybutadiene（ESPB） as coupling agent,cyclohexane as solvent by living anionic polymerization and grafting-onto technology. The SC-PB was subsequently hydrogenated by homogeneous catalysis（catalytic hydrogenation using nickel naphthenate/ triisobutyl aluminum）,to transform the SC-PB into the corresponding star-comb poly（ethylene-co-butene）(SC-PEB).The SC-PB was characterized by SEC-TALLS,;H NMR,DSC and WAXD techniques.The hydrogenation degree and crystallinity degree of SC-PEB were also determined.
