Method for producing polyarylene sulfide |
| abstract |
(57) [Problem] To continuously discharge a polymer phase and a solvent phase from a polymerization tank in a continuous polymerization process of a PAS, so that the PAS composition (concentration) in the polymerization tank is always constant. To provide a continuous polymerization method of polyarylene sulfide which is effective for improving and stabilizing the molecular weight. SOLUTION: In a method for continuously producing a polyarylene sulfide by reacting a sulfur source and a dihalogenated aromatic compound in an aprotic organic solvent, a polymerization reaction in which a polymer phase as a dispersed phase is spherical droplets. A method for producing polyarylene sulfide, comprising at least one step. |
