【摘要】 以苯酚、对二溴苯及苯基磷酰二氯为原料合成出二（4-苯氧基苯基）苯基氧磷（BPOPPO）。三氯化铝（Al Cl₃）为催化剂,通过缩聚反应,BPOPPO与对苯二甲酰氯（TPC）反应制备出一种含有三苯基氧磷结构的聚醚醚酮酮（P-PEEKK）树脂。采用傅里叶变换红外光谱仪（FT-IR）、差示扫描量热仪（DSC）、热重分析仪（TGA）和广角X射线衍射（WAXD）等技术手段对P-PEEKK树脂的结构和性能进行表征。结果表明,P-PEEKK树脂属于非晶聚合物,玻璃化转变温度（T_g）较高,为190.5℃;热分解温度(T_5%)为515℃,耐热性能较好;极限氧指数（LOI）为42,阻燃性能好,为难燃材料;易溶解于氯仿、1,2-二氯乙烷、N,N-二甲基乙酰胺等有机溶剂中,溶解性能较好,便于涂膜加工;拉伸强度为62 MPa,力学性能较好。更多还原

【Abstract】 A kind of poly（aryl ether ether ketone ketone）containing phenyl phosphine oxide structure（P-PEEKK）was synthesized by polycondensation of bis（4-phenoxy phenyl）phenyl phosphine oxide（BPOPPO）synthesized from phenol,1,4-dibromobenzene and phenylphosphonic dichloride as raw materials and terephthaloyl chloride（TPC）with aluminum chloride（Al Cl₃）as the catalyst.The structure and properties of P-PEEKK resin were characterized by Fourier transform infrared spectroscopy（FT-IR）,differential scanning calorimetry（DSC）,thermogravimetric analyzer（TGA）and wide-angle X-ray diffraction（WAXD）,etc.The results show that P-PEEKK resin is amorphous with a high glass transition temperature（T_g）of 190.5℃,a thermal decomposition temperature(T_5%)of 515℃,limiting oxygen index（LOI） of 42 and tensile strength of 62 MPa,and is soluble in chloroform,1,2-dichloroethane,N,N-dimethylacetamide and other organic solvents for coating film.更多还原
