摘要
聚磷腈是一类骨架由磷、氮单双键交替排列而成，侧基由有机基团组成的元素有机高分子，具有环状的和线型的结构特征。其合成方法主要有三种：一是先聚合再取代的合成路线；二是先取代再聚合的合成路线；三是用聚磷腈衍生物合成法和直接合成法合成。聚磷腈可用于制备耐性阻燃材料、特种橡胶与弹性体、高分子光学材料、分离膜、导电材料、染料与催化剂、分离膜等，应用广泛。
Polyphosphazenes is characterized by alternating phosphorous and nitrogen atoms in backbone with alternating double and single bonds. The method to synthesize has three kinds：first, come together and replace. second, replace first, then come together.Third, synthesize by polydichlorophosphazene.It has potentialapplications in biomaterials, flame retardants, liquid crystals, polymer electrolytes and electrooptics materials.
