摘要：

A bifunctional living poly(dimethylsiloxane), poly(DMS), was synthesized through the anionic ring-opening polymerization of hexamethylcyclotrisiloxane(D3) with an initiator system consisting of the dilithium salt of bis(p-hydroxydimethylsilyl)phenyl ether and N-methylpyrrolidine in THF solution. The subsequent end-capping reaction of the bifunctional living poly(DMS) with dimethylvinylchlorosilane provided the uniform-size poly(DMS) having vinylsilane groups at both chain ends.
