| titleOfInvention | Method for producing polyarylene sulfide resin |
| abstract | (57) [Problem] To provide a simple method for producing a polyarylene sulfide resin without using a polymerization aid at the time of polymerization and without having to control the water content of a polymerization system during the polymerization process, An object of the present invention is to provide a method for producing a polyarylene sulfide resin, which has a constant property of a polyarylene sulfide resin and has excellent filtration performance at the time of collecting a produced polymer. SOLUTION: In the method for producing a polyarylene sulfide resin by reacting an alkali metal sulfide with a dihalo aromatic compound in an organic amide solvent, the polyhalo aromatic compound is added to the alkali metal sulfide in an amount of 0 mol per mol of the alkali metal sulfide. .0 By adding 0.5 to 1.5 mol%, a part of the gas phase in the reaction vessel is condensed by cooling the gas phase part of the reaction vessel, and this is refluxed to the liquid phase. The rate of temperature rise up to the reaction temperature in the temperature range A method for producing a polyarylene sulfide resin which is controlled at a temperature of 1.0 to 1.0 ° C./min. |
