Production process for polyarylene sulfide |
摘要 |
Provided is a production process for polyarylene sulfide having a high molecular weight and an excellent heat stability. It is a production process for polyarylene sulfide by reacting a dihalogenoaromatic compound with metal sulfide in a polar solvent, wherein all or a part of water required for the reaction is added on a condition that the reaction system is 100° C. or higher, whereby obtained is polyarylene sulfide which is reduced in an intrinsic viscosity [eta] by 0.05 deciliter/g or less at 206° C. when added to an N-methyl-2-pyrrolidone solvent is the polyarylene sulfide of an amount equivalent to the solvent and it is maintained at 265° C. for 8 hours.
