摘要：

以六氯环三膦腈（HCCP）和4,4′-二羟基二苯砜（BPS）为共缩聚单体，乙腈为溶剂，三乙胺为缚酸剂，在室温条件下，采用沉淀聚合的方法快速合成了一种聚膦腈亚微米球。 红外光谱、元素分析及X射线能谱分析(EDX)测试表明，该聚膦腈亚微米球具有高度交联的化学结构；扫描电子显微镜和透射电子显微镜测试表明，该聚膦腈亚微米球粒径分布在410 nm附近，而且具有光滑的表面和实心的结构；热重分析(TGA)测试表明，该聚膦腈亚微米球的热分解温度达到531 ℃。 并推测了该聚膦腈亚微米球的形成机理。

Abstract:

Polyphosphazene(PPZ) sub-micrometer spheres were prepared rapidly under room temperature via precipitation polymerization of hexachlorocyclotriphosphazene(HCCP) with 4,4′-sulfonyldiphenol(BPS), using acetonitrile as the solvent and triethylamine(TEA) as the acid-acceptor. The PPZ sub-micrometer spheres were characterized by FT-IR, elemental analysis and EDX, and their highly cross-linked structures were identified. SEM and TEM results indicated that the PPZ sub-micrometer spheres had diameter of about 410 nm, solid structure and smooth surface. TGA result showed that the thermal decomposition temperature of the PPZ sub-micrometer spheres was about 531 ℃. In addition, the formation mechanism of the PPZ sub-micrometer spheres was proposed.

Key words: precipitation polymerization, polyphosphazene, microspheres, synthesis
