ABSTRACT:
Described are polysulfurized olefin compositions defined as being prepared by reaction of sulfur monochloride and/or dichloride with at least one monoolefin with 6 to 12 carbon atoms to form an addition product (or "adduct"), then by reaction of said adduct with a mercaptate or mercaptate-polysulfide of an alkaline metal or ammonium, itself obtained, for example, by reaction of a mercaptan with an alkaline hydroxide or with ammonia then, if need be, with sulfur, preferably in an alcoholic medium. These polysulfurized olefin compositions can be used as extreme-pressure additives in gearing oils or in oils for use in metal-working.
