Summary:The novel functionalized triblock copolymers,poly[（4-vinylphenyl）dimethylsilane]-b-polybutadiene-b-poly[（4-vinylphenyl）-dimethylsilane] （PVPDMS-b-PBd-b-PVPDMS）,were synthesized by anionic polymerization method using high vacuum technique. The hydrocarbon-soluble dilithium initiator synthesized from l,3-di[l-（methylphenyl）ethenyl]benzene（MPEB） was used to synthesize polybutadiene（PBd） precursors and the triblock copolymers in the presence of sec-BuOLi.The precursors and copolymers were characterized by size exclusion chromatography（SEC）,~1HNMR and DSC techniques.
