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(AlCl3) 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(Tg) of 190.5 ℃, a thermal decomposition temperature(T5%) 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.

Key words: bis(phenoxy phenyl) phenyl phosphine oxide, terephthaloyl chloride, poly(aryl ether ether ketone ketone)
