摘要

研究了下列含苯并噻唑环的芳香族二腈的环化三聚反应: (?)通过聚合条件的选择

得到的聚合物在371℃、在空气中200小时的失重约为15％

优于一般耐高温高分子

形变温度可以达到400℃以上

通过红外光谱分析

认为由氰基三聚环化生成了对称三嗪环。

Abstract

The cyclotrimerization of following aromatic dinitriles with benzothiazole ring were investigated:The weight loss of polymers obtained under optimum conditions at 371℃ (700°F) in air during 200 hours was about 15%. It was superior than ordinary heat-resistant polymers. Its deformation temperature was above 400℃. The formation of 1

5-triazine ring by cyclotrimerization of cyano group was verified by infra-red spectro-scopy.
