摘要： The application provides a process for producing a poly(arylene sulfide) comprising a dehydration step of heating and dehydrating a mixture containing an organic amide solvent (a), an alkali metal sulfide and water to control a water content in the mixture and a subsequent polymerization step of subjecting the alkali metal sulfide and a dihalo-aromatic compound to a polymerization reaction in the organic amide solvent (a), wherein hydrogen sulfide vaporized off during the dehydration step is absorbed in another organic amide solvent (b) outside a system in which the dehydration step is carried out, thereby recovering it, and the hydrogen sulfide thus recovered is reused in the polymerization reaction as a raw material for the alkali metal sulfide. The production process of the application can solve various problems attendant upon the vaporization of hydrogen sulfide and provide a poly(arylene sulfide) which undergoes little variation in melt viscosity and has stable quality.
