A method for preparing a highly heat-resistant and burning-resistant poly(silyleneethynylene phenylene-ethynylene) having a repeated unit represented by the following structural formula (lA) :
wherein the phenylene group may be in the o-, m- or p-form, R represents a halogen atom or an alkyl group, alkoxy group, phenoxy group, alkenyl group, alkynyl group, aromatic group, disubstituted amino group or silanyl group ; n is an integer ranging from 0 to 4 ; and R' represents a hydrogen atom, an alkyl group, alkenyl group, alkynyl group or aromatic group, a product obtained by the method and a hardened product obtained by heat-treating, at a temperature ranging from 50 to 700°C , the poly(silyleneethynylene phenyleneethynylene).
一种制备具有以下结构式(lA)代表的重复单元的高耐热性和耐燃烧性聚(硅亚乙炔-苯亚乙炔)的方法:
其中,亚苯基可以是邻型、间型或对型;R 代表卤素原子或烷基、烷氧基、苯氧基、烯基、炔基、芳香基、二取代氨基或硅烷基;n 是 0 至 4 之间的整数;R'代表氢原子、烷基、烯基、炔基或芳香基,通过该方法得到的产品和通过在 50 至 700°C 的温度下对聚硅烷基苯乙炔进行热处理得到的硬化产品。
