ABSTRACT:
A method by which p-phenylene sulfide polymers are produced by admixing p-dihalobenzene, an alkali metal sulfide, an organic amide, a lithium halide, and optionally, a base, at polymerization conditions thereby producing a polymer of higher molecular weight as evidenced by lower melt flow and higher inherent viscosity than is obtained without the addition of the lithium halide.
