摘　　要：以苯磺酰氯/吡啶/N,N-二甲基甲酰胺的混合物为缩合剂,采用双酚A与双(4-羧苯基)苯基氧化膦(BCPPO)通过高温溶液缩聚,制备了一种新型的双酚A型聚芳酯PAR-P,并与双酚A和对苯二甲酸反应制备的传统双酚A型聚芳酯PAR-T作为对照,系统研究了含磷聚芳酯的结构与性能。PAR-P和PAR-T的特性黏数分别为0.86和0.34 dL g 1;广角X射线衍射(WAXD)、差示扫描量热法(DSC)、动态力学分析(DMA)和热失重分析(TGA)测试结果表明:PAR-P为非晶聚合物,PAR-T为结晶聚合物;PAR-P比PAR-T具有更好的热稳定性;溶解性测试结果表明:PAR-P在常温或加热的条件下可以溶于常见的有机溶剂,但PAR-T溶解性较差。阻燃性测试结果表明:PAR-P具有良好的阻燃性能。With benzene sulfonyl chloride/pyridine/dimethyformamide as the condensation agent, a new type bisphenol-A polyarylates PAR-P was prepared through the high temperature solution polycondensation of bisphenol A with bis（4-carboxyphenyl） phenyl phosphine oxide （BCPPO）. Its structure and properties were studied systematically and compared with the traditional polyarylate of PAR-T which was synthesized by the reaction of bisphenol A with terephthalic acid （TPA）. The intrinsic viscosity of PAR-P and PAR-T are 0.86 and 0.34 dL.g-1, respectively. The results of wide-angle X-ray diffraction （WAXD）, differential scanning calorimetry （DSC）, dynamic mechanical analysis （DMA） and thermogravimetric analysis （TGA） show that： PAR-P is an amorphous polymer, while PAR-T belongs to crystalline polymer. The thermal stability of PAR-P is better than that of PAR-T, and the solubility test results show that the PAR-P can be dissolved easily in common organic solvents, but PAR-T has poor solubility. The limiting oxygen index （LOI） demonstrates that the PAR-P has excellent flame retardant property.
