The present invention relates to a method for producing low chlorine polyarylene sulfide. According to the method of the present invention, after polymerization of the polyarylene sulfide, instead of adding only the existing phase separation agent, water, an additive for substituting a polyarylene sulfide end group and a phase separation agent including water are added to effectively chlorine the polyarylene sulfide end group It relates to a method for producing low-chlorine polyarylene sulfide, which can be removed to improve processability. |
