摘　　要：为了获得较好性能的聚磷腈弹性体,用聚二氯磷腈为亲核取代基,三乙胺作为缚酸剂合成了交联型的聚磷腈无机高分子,利用红外光谱和元素分析对聚(苯氧基-一缩二乙二醇氧基磷腈)(聚合物Ⅰ)、聚(苯氧基-二缩三乙二醇氧基磷腈)(聚合物Ⅱ)进行了结构表征.结果表明,苯氧基和缩醇氧基都已经接入聚磷腈骨架,并形成含有氯原子的二维网状稳定结构,但聚磷腈中还是有少量的羟基存在.通过X射线衍射、热分析等性能研究表明,聚合物Ⅰ、Ⅱ都是非晶态高聚物,在空气中吸湿性小,热稳定性较好,具有非常优良的耐腐蚀和耐溶剂能力.To obtain polyphosphazenes inorganic elastomer with good mechanical and thermal properties, cross-linking polyphosp- hazenes was synthesized by using Polydichlorophosphazene as nucleophilic substitution reagent and triethylamine as acid binding a- gent. Structures of poly（phenyloxy-diethylene glycol phosphazene） （polymer I ） and poly（phenyloxy-triethylene glycol phosphazene） （polymer [[ ） were characterized by IR and Elemental analysis. The results showed., skeleton of polyphosphazene was two-dimensional network containing chlorine atoms, which connected by phenyloxy and glycoloyl, small amount of hydroxyl existed in polyphosphazene skeleton. Data of x-ray diffraction and thermal analysis showed that polymer I and polymer II were amorphous,hardly absorbed moisture,had good thermal stability and excellent eorrison and solvent resistance.
