摘要
以邻二甲苯为原料,经五步反应合成了四甲基[双(3,4二甲酸酐苯基)]二硅氧烷(Ⅴ).(Ⅴ)与八甲基环四硅氧烷平衡,得到含数个硅氧链段的芳香二酐.
Starting from 4 bromo o xylene,1,3 bis(3,4 dicarboxyphenyl) 1,1,3,3 tetramethyldisiloxane dianhydride(Ⅴ) was synthesized.(Ⅴ) was equilibrated with octamethylcyclotetrasiloxane used sulfuric acid as a catalyst,aromatic dianhydride containing siloxane was obtained.
