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.
