    摘要: A carboxylic composition comprising a mixture of hydrocarbon substituted carboxylic acylating agents, said mixture comprising (A) a polyolefin substituted carboxylic acylating agent prepared by reacting a polyolefin with an .alpha.,.beta.-unsaturated carboxylic reactant; and (B) a terpolymer substituted carboxylic acylating agent prepared by reacting a terpolymer with at least one carboxylic reactant selected from the group consisting of compounds of the formula R.sup.3 C(O)(R.sup.4).sub.n C(O)OR.sup.5 (IV) wherein each of R.sup.3 and R.sup.5 is independently H or a hydrocarbyl group, R.sup.4 is a divalent hydrocarbylene group, and n is 0 or 1, and reactive sources thereof, derivatives of the foregoing carboxylic compositions, with one or more of (1) an amine characterized by the presence within its structure of at least one HN
