The synthesis of epoxidized star-shaped polymers by incorporation of living anionic polymerization with polyhedral oligomericsilsesquioxane(POSS) is seldom reported. In this study, the living(polyisopryl)lithium(PI-Li) is first synthesized in cyclohexane via high-vacuum living anionic polymerization using sec-butyllithium as the initiator and isoprene as the monomer. Subsequently, PI-Li is used to react with octavinyl polyhedral oligomericsilsesquioxane(OVPOSS) in cyclohexane to prepare an eight-arm star-sh...
