Abstract: A composition comprising polysulfides, wherein at least about 50 wt. % of the polysulfides are branched C20 to C60 polysulfides represented by general formula R15S1—[S]n—S2R16 wherein R15 and R16 are each independently a branched C10 to C30 alkyl group and wherein n is an integer from 1 to 10. A process of producing a polysulfides crude product comprising one or more branched C20 to C60 polysulfides comprising: (A) reacting a feedstock comprising one or more branched C10 to C30 mercaptans and sulfur in the presence of a catalyst and (B) collecting the polysulfides crude product.

Abstract: A process comprising (a) beginning with a poly(arylene sulfide) polymer comprising a plurality of small poly(arylene sulfide) polymer particles and large poly(arylene sulfide) polymer particles, distinguishing at least a portion of the small poly(arylene sulfide) polymer particles from the large poly(arylene sulfide) polymer particles to yield distinguished small poly(arylene sulfide) polymer particles, wherein the small poly(arylene sulfide) polymer particles have a particle size of less than 2.38 mm and the large poly(arylene sulfide) polymer particles have a particle size of equal to or greater than 2.38 mm, and (b) contacting at least a portion of the distinguished small poly(arylene sulfide) polymer particles with an aqueous solution to form treated small poly(arylene sulfide) polymer particles.
