[ What is claimed is:] [1.] A lubricating composition comprising a major amount of an oil of lubricating viscosity and a minor amount of a composition prepared by a process comprising first reacting, optionally in the presence of an acidic catalyst selected from the group consisting of organic sulfonic acids, heteropolyacids, Lewis acids, and mineral acids,(A) at least one olefinic compound containing at least one group of the formula [ STR 14 ] wherein the olefinic compound has the general formula (R.sup.1)(R.sup.2)C.dbd.C(R.sup.6)(CH(R.sup.7)(R.sup.8)) (III) wherein each R.sup.1 and R.sup.2 is, indepently, hydrogen or hydrocarbon based group, and each of R.sup.6, R.sup.7 and R.sup.8 is, indepently, hydrogen or hydrocarbon based group; and(B) at least one carboxylic reactant selected from the group consisting of compounds of the formula EQU R.sup.3 C(O)(R.sup.4).sub.n C(O)OR.sup.5 (IV) compounds of the formula [ STR 15 ] wherein each of R.sup.3, R.sup.5 and each R.sup.9 is independently H or a hydrocarbyl group, R.sup.4 is a divalent hydrocarbylene group, and n is 0 or 1, in amounts ranging from 0.6 moles (B) per mole of (A) to 1.5 moles (B) per equivalent of (A); and from about 0.5 to about 2 moles, per mole of (B), of(C) at least one aldehyde or ketone, then reacting the product formed thereby with from about 0.5 equivalents up to about 2 moles, per mole of (B) of at least one of(D) ammonia or a hydrazine or an amine characterized by the presence within its structure of at least one H--N group.
