Abstract: Mixtures of the reaction product of at least one C5-C60 carboxylic acid and at least one amine selected from the group consisting of guanidine, aminoguanidine, urea, thioruea and salts thereof and a phosphorus-containing dispersant are useful as gear oil additives. Lubricant formulations containing said mixtures exhibit excellent low and high temperature rheology and are particularly suited for use in automotive and industrial gear applications. Lubricants of the present invention exhibit improved performance properties such as increased axle efficiencies and lower axle temperatures compared to lubricant formulations that do not contain said mixtures.
Abstract: Reaction products of i) a hydroxyl-group containing compound; ii) an amine-group containing compound, wherein component ii) is different from component i); and iii) a hydrocarbyl-substituted succinic acylating agent provide improved detergency as well as improved lubricity to hydrocarbon fuels. Compositions comprising a hydrocarbon fuel and the reaction products are also disclosed.
Abstract: Block copolymers having a molecular weight distribution of between 1.0 and 5.0 comprising at least one block of polymerized alkyl methacrylate monomer(s), wherein from 50 to 100% by weight of the monomers for forming the alkyl methacrylate block are C12-C30 alkyl methacrylates, and a block of a polymerized conjugated alkadiene. The block copolymers of the present invention are useful as viscosity index improvers in lubricating oil compositions as well as compatibilizers for compositions containing both polymethacrylates and olefin copolymers or hydrogenated block polymers.
