    摘要: The present invention is a process for the production of polyarylene sulfide based resin, wherein in washing a polyarylene sulfide based resin with a mixed solvent of an aprotic organic solvent and water in a softened or molten state, the polyarylene sulfide based resin partially dissolved in the washing liquid is recovered, to be specific, the polyarylene sulfide based resin dissolved in the washing liquid is precipitated, separated and recovered by cooling the washing liquid after washing and/or adding water to the washing liquid, and it is reused. According to the present invention, capable of being provided is a process for the production of polyarylene sulfide based resin in which the polyarylene sulfide based resin formed by polymerization is scarcely lost in washing the above resin with a solvent.
