ABSTRACT:
A process for the catalytic self-condensation of halothiophenol to form a poly(arylene sulfide) is disclosed. The reaction mixture includes an alcohol solvent, the halothiophenol, an alkaline reagent and a catalyst comprising a Group VIII metal. The polymerization process can be carried out at pressures as low as 1 atmosphere and temperatures of 200.degree. C. or less.
