| titleOfInvention | Method for producing polyarylene sulfide |
| abstract | An object of the present invention is to provide a method capable of efficiently producing a linear high molecular weight PAS in a short time. A method for producing polyarylene sulfide includes at least the following steps 1 and 2. Step 1: an alkali metal sulfide containing 1 mol or more of water per 1 mol of a sulfur component is dehydrated in the presence of 0.05 to 0.6 mol of an organic polar solvent per 1 mol of a sulfur component of the alkali metal sulfide. A step of preparing a sulfidizing agent containing 0.05 to 0.6 moles of water per mole of the component, step 2: combining the sulfidizing agent prepared in step 1 and the dihalogenated aromatic compound with an organic carboxylic acid metal salt, At least one compound selected from the group consisting of an aromatic cyclic amine compound, an N-heteroaromatic compound, and an organic sulfoxide compound, and polymerization in the presence of 0.05 to 0.6 mol of water per 1 mol of a sulfur component of a sulfidizing agent Process to make it.
