摘　　要：用“顺点滴式”方法改进了单体合成 ,较原“全混式”提高了产率 ,降低了消耗 ;用Wurtz法以二氯硅烷和三氯硅烷为原料 ,经“预聚”和“混聚”Synthesis of the monomers was improved by using the 'sequential drop'. By this way the yield of the monomers was increased, and the drain of the materials were decreased as compared with 'fully mixing'.Using Wurtz-type coupling of methylphenethyldichlorosilane and trichloromethylsilane branched polysilanes ∶ P(MPES-co-MS) were synthesized by 'pre-polymerization' and 'mixing polymerization'.

关 键 词：“顺点滴式” “全混式” “预聚” “混聚” 枝状聚硅烷 合成 表征 Wurtz法 二氯硅烷
