Abstract (en)
A lubricating composition comprises a major amount of an oil of lubricating viscosity and a minor amount of one or more carboxylic derivatives obtainable by reacting at least one substituted succinic acylating agent, which acylating agent comprises a copolymer of an aliphatic olefin and a monomer having the structure: X - @ - HC = CH - @ - X<1> (I) wherein X and X<1> are the same or different provided at least one of X and X<1> is such that the substituted succinic acylating agents can function as carboxylic acylating agents with a reactant selected from (a) an amine having within its structure at least one H-N group, (b) an alcohol, (c) a reactive metal or a reactive metal compound, and (d) a combination of two or more of any of (a) to (c). The preferred aliphatic olefin is a C4-C30 aliphatic olefin for example octadecene-1. The preferred monomer is maleic anhydride. Preferred amines comprises C10-C18 primary monoamines.
