| titleOfInvention | Process for producing polyarylene sulfide and granular polyarylene sulfide |
| abstract | An object of the present invention is to obtain a granular PAS having high melt fluidity, a large weight average particle diameter, and excellent handling. In an organic polar solvent, an organic carboxylic acid metal salt, an alkali metal chloride (except sodium chloride), an organic sulfonic acid metal salt, an alkali metal sulfate, an alkaline earth metal oxide, an alkali metal phosphorus Polyarylene by reacting a sulfidizing agent with a dihalogenated aromatic compound in a temperature range of 200 ° C. or higher and lower than 280 ° C. in the presence of at least one compound selected from acid salts and alkaline earth metal phosphates In the production of sulfide, the dihalogenated aromatic compound is charged in an amount of 102 mol to less than 110 mol with respect to 100 mol of the sulfidizing agent, and <Step 1> within a temperature range of 245 ° C. to less than 280 ° C. Reaction is performed for 5 minutes or more and less than 80 minutes, and <Step 2> Following Step 1, PAS is recovered by a quench method. [Selection figure] None |
