【摘要】 将光敏基团Cl直接键连在聚硅烷大分子上,用3种方法合成了含氯聚硅烷:①用硅氢化反应将氯丙烯加成到聚硅烷上;②用含苯基聚硅烷中的苯环进行氯甲基化反应;③在Wurtz缩合反应完成后直接从反应体系中将端基含氯的聚硅烷分离出来.对产物分别进行了1HNMR、FT IR、GPC和XPS表征.更多还原

【Abstract】 The photosensitivity radicalCl was directly bonded with polysilane molecules. The polysilanes containing chlorine were synthesized by three ways: ①Through hydrosilylation reaction the propylene chloride was added to polysilanes containing Si-H. ②The containing chlorine polysilanes were synthesized by chloromethylation reaction of polysilanes with Ph. ③After complete of Wurtztype reductive condensation, the polysilanes with endCl directly were separated from reaction system. The polysilanes containing chlorine were characterized and analyzed by the 1HNMR, FTIR, GPC and XPS.更多还原
