摘要
从4-溴-1,2-二甲苯出发,经过三步反应合成了双-(3,4-苯二甲酸酐)二甲基硅烷单体,总产率为24.7％;由该单体与4,4’-二氨基二苯醚共聚合,经环化脱水反应得含硅聚酰亚胺,并对该共聚物进行了初步表征。
Monomer bis(3,4-dicarboxyphenyl)dimethylsilane dianhydride was synthesized from 4-bromo-1,2-dimethyl-benzene and dichlorodimethylsilane through Wurtz coupling reaction , oxidization and cyclization reaction with the overall yield of 24. 7% . And bis(3,4-dicarboxyphenyl)dimethylsilane dianhydride was copolymerized with 4,4'-diaminodiphenyl ether in the N.N '-dimethylacetamide . The corresponding polyimide was characterized by FTIR and WAXD as well as UV-Vis .
