摘　　要：合成了三种新的甲基(β-三烷基硅乙基)二氯硅烷,以新的二氯硅烷和甲基苯基二氯硅烷为原料,用在甲苯中以金属钠共缩合的方法,通过均聚和共聚反应,合成了8种新型聚硅烷.测定了这些聚硅烷的分子量,讨论了它们的红外、紫外和核磁共振光谱吸收性质.With methylvinyldichlorosilane, methyldichlorosilane and various primary alkylhalides as starting agents, methyl (β-trialkylsilylethyl) dichlorosilanes were prepared via Grignard reaction and hydrosilation. New organosilane polymers containing β-trialkylsilylethyl side group were synthesized by sodium coupling of diorganodichlorosilares in toluene. The polymers of CH_3(R_3SiCH_2CH_2)SiCl_2 are flowable, and the copolymers of CH_3(R_3SiCH_2CH_2)SiCl_2 with CH_3PhSiCl_2 are elasto-viscous states. The structure and physical constants of organodichlorosilanes were determined, and the molecular weight, infrared, nuclear magnetic resonance and ultraviolet spectra for the organosilane polymers were described.
