Abstract: 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.

Abstract: Thermoplastic compositions are described that exhibit resistance to hydrocarbon absorption. Methods for forming the thermoplastic compositions are also described. Formation methods include combining a polyarylene sulfide with a first impact modifier and a second impact modifier such that the impact modifiers are dispersed throughout the polyarylene sulfide. A crosslinking agent can be combined with the other components of the composition following dispersal of the additives throughout the composition to dynamically crosslink at least one of the first and second impact modifiers.
