采用具有不同有机取代基的二氯硅烷与甲基二苯基氯硅烷为原料,在甲苯中以金属钠共缩合的方法,合成了可流动的聚硅烷。这些聚硅烷可用灌注、浇铸、涂敷等方法制成各种形状,并能在多乙烯基硅烷存在下,以紫外光辐照进行交联。本文还讨论了这些聚硅烷的分子量分布以及红外、紫外、核磁共振等光谱性质。 Using a mixture of dichlorosilane and methyldiphenylchlorosilane with different organic substituents as the raw materials and co-condensation of sodium metal in toluene, a flowable polysilane was synthesized. These polysilanes can be made into various shapes by potting, casting, coating and the like, and can be crosslinked by irradiation with ultraviolet rays in the presence of polyvinylsilane. We also discuss the molecular weight distribution of these polysilanes as well as their spectral properties such as infrared, ultraviolet, and nuclear magnetic resonance.
