摘　　要：以甲基乙烯基二氯硅烷为单体,采用超声钠缩合法合成聚(甲基-乙烯基)硅烷;在此基础上,采用相同的方法,变化单体以甲基乙烯基二氯硅烷和甲基苯基二氯硅烷为原料,合成了共聚硅烷和有一定程度交联的聚甲基乙烯基硅烷,并对它们用FT-IR,1HNMR,UV,TGA进行了表征.结果表明,聚(甲基-乙烯基)硅烷产物产率从2%提高到了28%;各种产物聚硅烷中均含有大量乙烯基基团,有利于进一步进行其他官能化反应.Polymethylvinylsilane was synthesized in the ultrsonic coupling method using dichloromethylvinylsilane as the monomers. The poly（methlvinylsilane-co-methylphenylsilane） and the crosslinked polymethylvinylsilane were synthesized in the same method. They were characterized by FTIR,^1HNMR, UV and TGA. The results showed that the yield of polymethylvinylsilane rose from 2 % to 28 %, and the polysilanes contained vinyl, which was capable of being further functionalized.
