Summary

High molecular weight poly(phenylene sulfide sulfone/phenylene sulfide ketone) copolymer was synthesized by the step polycondensation of sodium sulfide (Na2S·xH2O) with 4,4′-dichlorobenosulfone (DCDPS), 4,4′-difldibenzophenone (DFBP) between 180∼202 °C at normal pressure. The copolymer was characterized by FT-IR spectrum, UV spectrum, 1H-NMR spectrum, X-ray diffraction and small angle light scattering (SALS), DSC and TGA. The more ketone in the copolymer chain, the better thermal properties of the PPSS/Ks resins have. The copolymer was found to be amorphous but has little local ordering structures with the content of ketone in the range of 0∼45% which is different from other high pressure polymerization.
