ABSTRACT:
A process for preparing arylene sulfide polymers by dehydrating an aqueous mixure of a sulfur source and a cyclic organic amide to form a dehydrated mixture, contacting the dehydrated mixture with a dihaloaromatic compound to produce a polymerization mixture, polymerizing the polymerization mixture and recovering the arylene sulfide polymer wherein the process is conducted in the presence of a compound selected from the group consisting of unsubstituted aromatic hydrocarbons, alkyl-substituted aromatic hydrocarbons, alkyl ethers, aryl ethers, alkyl-aryl ethers, polyethers and saturated aliphatic hydrocarbons.
