聚苯氧基磷酸对苯二酚酯的合成、表征及其热稳定性研究

Synthesis,characterization and thermal stability of poly(hydroquinone phenyl phosphate)

以三氯氧磷、苯酚和对苯二酚为主要原料,通过两步合成法,采用本体聚合制备了含磷阻燃剂聚苯氧基磷酸对苯二酚酯。使用红外光谱、1 HNMR、13C NMR和31P NMR确定了阻燃剂的结构。用热重分析测试了阻燃剂的热稳定性。结果表明,聚磷酸酯的结构与预期结构相符;其初始分解温度为364℃,最快分解温度为547℃,700℃时的残炭量为36%,表现出良好的热稳定性。

The flame retardant,poly（hydroquinone phenyl phosphate） was prepared by bulk polymerization with phosphorus oxychloride,hydroquinone and phenol in two step procedure.The structure of polymer was confirmed with FT-IR,1H NRM,13C NMR and 31P NMR spectrum.Thermal stability of polymer was investigated with thermogravimetric analysis.The result showed that structure of polymer was agree to expect.The polymer showed good thermal stability by giving initial decomposition temperature of 364℃;the fastest decomposition temperature of 547℃;and 36% residua at 700℃.
