摘要
采用传统的亲核取代反应的方法合成了一种新的含有咔唑侧基的有机磷腈高分子 ,并用红外、1 H核磁、紫外、热失重、差热分析了其结构 .它的玻璃化转变温度为 91 .6℃ ,大大低于聚乙烯咔唑 (PVK)的玻璃化转变温度 .
In this paper, we synthesized polyphosphazene with pendant carbazolyl groups, and characterized its structure by IR, 1H NMR, UV spectroscopy, TGA, DTA. Due to high thermal stability of polydichlorophosphazene, it increased T d of organic molecules. On the other hand, its T g decreased by more than 50 ℃ in comparison with PVK because of the flexible property of main chain. In addition, only the absorption of carbazole groups was observed, which means there is no absorption for main chain in this range. [WT5HZ]
