| Abstract: | A star-shaped multifunctional styrene-isoprene copolymer was synthesized with n-BuLi as initiator, divinyl benzene as coupling agent, cyclohexane as solvent by living anionic polymerization. Using this polymer as grafting agent, a novel star-shaped branched polymer, containing several polyisobutylene, was prepared via cationic polymerization. The star PS-b-PI and star-branched polyisobutylene were characterized by GPC, 1HNMR and FT-IR, and the effects of different adding order and the amount of grafting agent were investigated. |
