Polycondensation of 4,4’-dichlorodiphenyl sulfone with sodium sulfide gave a linear polyarylene sulfide sulfone. With dimethyl sulfoxide as solvent, sodium carbonate as catalyst, the reaction can be carried out at atmospheric pressure and lower temperature, the yield is over 90%. The product has a molecular weight of about 10,000, a logarithmic specific viscosity of about 33 cm -3 / g, a melting temperature of 250-270 ° C, a thermal decomposition temperature of 465 ° C, and an apparent thermal decomposition activation energy of 37.8 kcal / mol. Elemental analysis, infrared spectrum and nuclear magnetic resonance show that the main structure of the polymer is; X-ray diffraction shows that the polymerization is partially crystalline.
