    摘要: Olefin polysulfide compositions of high sulfur content and of very low chlorine content are obtained by a process comprising the steps of: (1) reacting sulfur mono- and/or dichloride with at least one aliphatic monoolefin of 2-12 carbon atoms, to form an addition product or "adduct", (2) reacting hydrogen sulfide with an alkali hydroxide or ammonium hydroxide dissolved in at least one substantially anhydrous C.sub.1 -C.sub.4 aliphatic monoalcohol, with optional addition of elemental sulfur, (3) contacting said "adduct" together with at least one monohalogenated hydrocarbon compound, with the alcoholic solution obtained at the end of step (2), (4) heating the resultant mixture from step (3), removing the monoalcohol, while adding water, and (5) after settling and removal of the aqueous phase, recovering the organic phase formed at least in major part of the desired olefin polysulfide composition. These compositions, of sulfur content up to 65% by weight and of chlorine content generally lower than about 0.1% by weight, are used in particular as additives for improving the extreme-pressure properties of lubricants.

    摘要: Compositions of copolymers are disclosed containing 10 to 35% by weight of units derived from at least one vinylaromatic monomer, 5 to 15% by weight of units derived from at least one linear or branched alkyl methacrylate with 1 to 4 carbon atoms, 20 to 50% by weight of units derived from at least one linear alkyl methacrylate with 8 to 14 carbon atoms and 15 to 50% by weight of units derived from at least one linear alkyl methacrylate with 16 to 22 carbon atoms. The copolymer compositions have a weight average molecular weight of 100,000 to 400,000 and a polydispersity index in general of less than 5.They are prepared by any free-radical copolymerization method using for example azo or peroxide initiators.These compositions have the advantage of providing a better compromise between the characteristics required of a viscosity additive for lubricating oils.
