ABSTRACT:
A method is provided for producing p-phenylene sulfide polymers by contacting at least one p-dihalobenzene, at least one alkali metal sulfide, at least one organic amide and at least one alkali metal sulfonate at polymerization conditions. The use of an alkali metal sulfonate in addition to the other compounds contacted to form the reaction mixture results in a p-phenylene sulfide polymer of higher molecular weight than is produced without the alkali metal sulfonate, as evidenced by higher inherent viscosity and lower melt flow of the polymer than produced by the compared methods.
