摘要
以PCl5和NH4Cl为原料采用"一步法"合成了线型聚二氯磷腈(4);4与6-咔唑基己醇发生亲核取代反应合成了聚双(6-咔唑基己氧基)磷腈(5),其结构经1H NMR,31P NMR,IR和GPC表征。热分析结果表明,5具有良好的热稳定性和较高的玻璃化温度。
Poly[bis（hexan N-carbazol）]phosphazene（5） was synthesized by nucleophile substitution reaction of hexan N-carbazol with linear polydichlorophosphazene which was straightly prepared by ＂one step＂ method from PCl5 and NH4Cl.The structure was characterized by 1H NMR,31P NMR,IR and GPC.The thermal analysis test results showed that 5 exhibited good thermal stability and a higher Tg.
