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。 The following cyclization trimerization of benzothiazole ring-containing aromatic dinitriles has been studied: (?) The polymer obtained at 371 ° C by weight under conditions of polymerization has a weight loss of about 15% at 200 hours in air, In the general high temperature polymer, the deformation temperature can reach above 400 ℃, by infrared spectroscopy, that the cyclization of cyano trimerization to generate a symmetrical triazine ring.
