Abstract:
1. A production process of a poly(arylene sulfide), comprising the following steps: (1) a polymerization step of subjecting at least one sulfur source selected from the group consisting of alkali metal sulfides and alkali metal hydrosulfides and a dihalo-aromatic compound to a polymerization reaction in an organic amide solvent; (2) a reaction step of adding a hydroxyl group-containing organic compound containing no bonded halogen atom in a proportion of 0.001 to 20 mol per 100 mol of the charged sulfur source into the polymerization reaction system containing the organic amide solvent and a polymer formed in the polymerization step after the polymerization step to cause the formed polymer to react with the hydroxyl group-containing organic compound; and (3) a collecting step of collecting a polymer formed in the reaction step from the polymerization reaction system containing the formed polymer after the reaction step.
