摘要: 利用六氯环三磷腈热开环聚合得到聚二氯磷腈, 通过亲核取代制备了聚苯氧基磷腈(PPP), 采用 NM R(31 P, 1 H , 13 C), FT -IR, TGA 等对其结构和性能进行了表征和分析, 裂解色谱-气相色谱-质谱对聚苯氧基磷腈的热裂解机理进行了探讨研究。结果表明, 聚苯氧基磷腈具有很好的耐热性能, 在高温阶段存在不同的热分解模式, 在400 ℃时主要为侧基的断裂, 500 ℃以上主要为主链的断裂。

Abstract:

Polyphenoxyphosphazene(PPP) was prepared from nucleophilic substitute reaction poly-(dichlorophosphazene),which was synthesized by thermal ring-open polymerization through hexachlorocyclotriphosphazene. The structure and property of PPP were analyzed by FT-IR, NMR, TGA. Pyrolysis mechanism of PPP was discussed by pyrolysis gas chromatography-gas chromatography-mass spectrometry. The results show that PPP has good heat resistance and has different thermal decomposition mode in high temperature, the side groups fracture at 400 ℃, main chain fracture above 500 ℃.
