Study on the Triaryl s Triazine Ring Cross linked High Temperature Polymers I.[ZnCl 2·Ce(SO 4) 5·NH 4]Trimerization Catalysts

三芳基联三嗪交联（ＴＳＴＲ）高温聚合物，可以通过芳基腈改进的齐聚物催化三聚反应来制备。大量的实验室研究发现，使用合适的复合阳离子型催化剂，在适当的条件下，如常压和小于３００℃，能够实现苯基腈三聚反应。本文还讨论了三聚反应机理及在不同湿度条件下的水解稳定性。

Triaryl s triazine ring cross linked (TSTR) high temperature polymers may be obtained through catalytic trimerization of aromatic nitrile modified digomers of interest. A suitable compound cationic catalyst has been found which would effect the trimerization of benzonitrile under a moderate condition such as <300℃ and normal pressure. The trimerization mechanism and hydrolysis stability under different moist conditions are also discussed.
