<p>Methods for forming a low chlorine content washed polyarylene sulfide are described. Methods include washing a polyarylene sulfide that includes aryl halide endgroups with a solution that includes a disulfide compound. The solution can also include a catalyst and an organic solvent. During the disulfide wash, a nucleophilic substitution reaction occurs between the disulfide compound and aryl halides endgroups of the polyarylene sulfide. The nucleophilic substitution reaction is carried out at conditions to prevent chain scission of the polyarylene sulfide that includes the aryl halide endgroups. Compositions and products formed with the low chlorine content disulfide washed polyarylene sulfide are also described.</p> |
