Abstract: An eight-arm star-shaped thermoplastic elastomer copolymer and a preparation method therefor; a polystyrene-polyisoprene lithium compound and a polystyrene/diphenylethylene-polyisoprene lithium compound are synthesized by using active anionic polymerization, and the compounds are then used for a coupling reaction with octenyl polyhedral oligomeric silasesquioxane to obtain an eight-arm star-shaped copolymer. The method has the characteristics of convenient operation, high reaction efficiency, mild reaction conditions, and few side reactions. The structure and molecular weight of the prepared eight-arm star-shaped polymer are controllable, and the molecular weight distribution is narrow. A polymer segment obtained by the copolymerization of diphenylethylene (DPE) and styrene (St) is used as a hard segment, which enables the eight-arm star-shaped thermoplastic elastomer copolymer to have more outstanding mechanical properties. At the same time, a polymer segment composed of DPE and St units has a higher glass transition temperature than polystyrene, which can increase the upper limit usage temperature of the eight-arm star-shaped thermoplastic elastomer copolymer.
