Abstract

We have developed the synthetic strategy of well-defined asymmetric star-branched polymers containing poly(dimethylsiloxane) segments by a coupling reaction of polymer bearing an anionized 1,1-diphenylethylene moiety and in-chain-functionalized poly(dimethylsiloxane) with a benzyl chloride group. Expectedly, 4-arm A₂B₂, ABC₂, and 5-arm AB ₂C₂ asymmetric star-branched polymers containing poly(dimethylsiloxane) were quantitatively synthesized by the coupling reactions. Their high degrees of compositional and architectural homogeneity were confirmed by the analytical results of SEC, ¹H NMR, and RALLS.
