Abstract:
The present invention relates to a lubricating composition comprising an oil of lubricating viscosity and a (thio)phosphate salt of an amine-functionalized esterified copolymer, wherein the esterified copolymer comprises units derived from monomers: (i) an ±-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof, that are esterified with an alcohol, or mixtures thereof, and wherein at least a portion of carboxylic acid groups not esterified react with an amine. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of lubricating composition in a mechanical device.
Abstract:
The present invention relates to a lubricating composition containing (a) an oil of lubricating viscosity; and (b) a heterocycle having a hydrocarbyl group containing 6 to 40 carbon atoms. The invention further provides for a method of supplying an internal combustion engine with the lubricating composition.
Abstract:
The present invention relates to a copolymer comprising units derived from monomers (i) an a-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified with a primary alcohol branched at the ss- or higher position, wherein the copolymer has a reduced specific viscosity of up to 0.08. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the copolymer with pendant groups. In addition, the copolymer of the present invention may be useful as a base oil replacement.
