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 .
A new kind of organic phosphazene polymer containing carbazole side groups was synthesized by the traditional nucleophilic substitution reaction and its structure was analyzed by infrared, 1 H nuclear magnetic resonance, ultraviolet (UV), thermogravimetry and differential thermal analysis. Its vitrification The transition temperature is 91.6 ℃, much lower than the glass transition temperature of polyvinyl carbazole (PVK).
