Abstract
A process for the production of arylene sulfide polymers is provided which comprises subjecting a mixture of at least one sulfur source, at least one organic monohalo compound, at least one polyhalo-substituted aromatic compound and at least one polar organic compound to polymerization conditions sufficient to produce the arylene sulfide polymer. The organic monohalo compound can be added at any time prior to substantial completion of polymerization to provide arylene sulfide polymers of increased extrusion rate.
