Patent ID: 8883959

Claim:
A method for producing a polyarylene sulfide resin, comprising, as essential production steps, step 1: a step of producing a slurry (I) containing a solid alkali metal sulfide by allowing a hydrous alkali metal sulfide, or a hydrous alkali metal hydrosulfide and an alkali metal hydroxide, and an aliphatic cyclic compound (c1) that can be ring-opened by hydrolysis to react with each other while conducting dehydration in the presence of a non-hydrolyzable organic solvent; step 2: a step of further adding an aprotic polar organic solvent after the production of the slurry (I), and distilling off water to conduct dehydration; and step 3: a step of conducting polymerization by allowing a polyhaloaromatic compound (a), an alkali metal hydrosulfide (b), and an alkali metal salt (c2) of a hydrolysate of the compound (c1) to react with each other in the slurry (I) obtained through the dehydration step of the step 2 in a state where the amount of water existing in the reaction system is 0.02 moles or less relative to 1 mole of the aprotic polar organic solvent.
