ABSTRACT:
A method is provided for producing p-phenylene sulfide polymers by contacting a p-dihalobenzene, an alkali metal sulfide, an organic amide, and a lithium salt selected from among lithium carbonate and lithium borates at polymerization conditions. The use of the lithium carbonate or lithium borates in addition to the other compounds contacted to form a composition results in p-phenylene sulfide polymers of higher molecular weight than produced without the lithium compounds, as evidenced by higher viscosity and lower melt flow of the polymer than produced by compared methods.
