Abstract: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, (1)H NMR, DSC and WAXD techniques. The hydrogenation degree and crystallinity degree of SC-PEB were also determined. (C) 2009 Yang Li.
