ABSTRACT:
A composition comprising (A) an ethylene-alpha olefin-bicyclic non-conjugated diene copolymer, wherein the alpha olefin contains from 3 to about 24 carbon atoms; (B) at least one organic sulfur containing compound selected from the group consisting of mercaptans and disulfides; and (C) a major amount of diluent; wherein the sulfur-containing compound (B) is present in amounts ranging from about 0.1% to about 15% by weight relative to the weight of the copolymer (A). This invention also relates to a method of shearing a composition comprising (A) an ethylene-alpha olefin-bicyclic non-conjugated diene copolymer and (C) a diluent, the improvement which comprises reducing or preventing the formation of gel-like particles on shearing by intimately mixing with said copolymer prior to shearing an amount of (B) an organic sulfur containing compound selected from the group consisting of mercaptans and disulfides in an amount sufficient to inhibit formation of said gel-like particles. The invention also relates to lubricating oil compositions containing the compositions of the invention.
