中文摘要：

以环状三聚六氯磷腈（HCCP）为原料，采用热开环聚合方法，合成了聚二氯磷腈，再利用亲核取代反应合成了聚苯氧基膦腈（PPPh）。采用FT—IR、^1H NMR、GPC、DSC、TGA等对所得到的聚合物进行了结构表征和性能测试。通过静电纺丝法制备聚苯氧基膦腈纤维，研究了纺丝液浓度、电场强度、挤出速度等对纤维形态的影响。结果表明，在聚合物溶液浓度为7（wt）％～8（wt）％、挤出速度为0．3～1．0mL／h、接收距离为20cm、电压为22kV的静电纺丝条件下，可制备纤维直径为300～800nm的PPPh纤维。

英文摘要：

Poly（bisphenoxy） phosphazene （PPPh） was synthesized by the reaction of sodium phenolate with linear poly （ dichlorophosphazene ）, which was obtained from hexachlorocyclotriphosphazene by thermal initiated ring-open polymerization. The polymer was characterized with FT-IR, ^1H NMR, GPC, DSC and TGA. Fibers of poly（bisphenoxy） phosphazene （PPPh） were prepared through electrospinning from solutions in chloroform. The effect of process parameters such as concentration of the polymer solution, applied potential and extrusion rate on the morphology （bead or bead free） of resulting fibers was investigated. It was found that the PPPh fiber with diameter of 300 - 800nm could be obtained by electrospinning under the conditions of PPPh mass fraction 7 （wt）% - 8 （wt）%, extrusion rate 0.3 - 1.0 mL/h, deposition distance 20 cm, and voltage 22kV.
