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 Cl_3)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。
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(AlCl 3)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.
