ABSTRACT:
A process is provided for producing a high molecular weight poly(arylene sulfide) polymer employing at least one dihaloaromatic compound, a sulfur source, a polar organic compound, a lithium salt which is soluble in the polar organic compound, and water in an amount less than about 1.75 moles of water per mole of sulfur under polymerization conditions. The pressure and temperature are chosen to allow the volatile reactants to be maintained in liquid form in the reaction mixture.
