自五十年代以来,耐热的杂环高分子取得了很多进展。曾报道聚酰亚胺、聚苯并咪唑、聚苯并噻唑、聚苯并噁唑、聚喹噁林及聚苯并噁嗪酮等都是性能较好的耐热高分子,而有些在工业上已得到应用。我们在进行芳杂环二腈聚合的工作中,曾将上述杂环结构引入二腈,以期获得性能优良的耐热高分子,所得结果已陆续报道。 Since the 1950s, many advances have been made in heat-resistant heterocyclic polymers. It has been reported that polyimide, polybenzimidazole, polybenzothiazole, polybenzoxazole, polyquinoline and polybenzoxazinone are all good performance heat-resistant polymers, and some in the industrial Has been applied. We are in the work of aromatic heterocyclic dinitrile polymerization, the heterocyclic structure was introduced into the two nitrile, in order to obtain excellent performance of heat-resistant polymers, the results have been reported.
