聚甲基苯基硅烷及其共聚物的合成与表征
Synthesis and Characterization of Polymethylphenylsilane and Its Copolysilane
【摘要】 用格氏法合成了甲基苯基二氯硅烷 ,并用钠缩合法将它均聚或分别与二甲基二氯硅烷、二苯基二氯硅烷、甲基乙烯基二氯硅烷等共聚 ,合成了 4种聚硅烷。用IR、UV、1H -NMR和GPC对它们进行了表征
【Abstract】 s:Methylphenyldichlorosilane was synthesized by Grignard reagent. Polymethylphenylsilane, poly(methylvinylsilane co methylphenylsilane), poly(dimethylsilane co methylphenylsilane) and poly(diphenylsilane co methylphenylsilane) were synthesized by the method of the Na reductive coupling. The structures of the polymers were characterized by means of UV, 1H-NMR,IR and GPC.
