    摘要: A process for producing a dispersant/VI improver for use in finished lubricating oil compositions comprises reacting in a normally liquid substantially inert organic solvent (a) a copolymer of an olefin and a monomer having the structure (I), wherein X and X.sup.1 are the same or different provided that at least one of X and X.sup.1 is such that the copolymer can function as carboxylic acylating agent, (b) a succinimide, and (c) a primary or secondary amine or a mixture thereof. Preferred copolymers comprise maleic anhydride as a comonomer. In a preferred embodiment of the invention, the amine is a monoamine, and a polyamine is also added; the monoamine and polyamine are added to the reaction medium prior to addition of the succinimide.

    摘要: A process for producing a lubricating oil dispersant additive comprises:step (1) reacting compound (A), wherein compound (A) is a hydrocarbyl-substituted or a substituted hydrocarbyl-substituted succinic acid or anhydride or ester thereof, with compound (B) of formula (I)H.sub.2 N(CHR.sup.1 CHR.sup.2 O).sub.n CHR.sup.3 CHR.sup.4 NH.sub.2 (I) wherein one R.sup.2 and R.sup.2 is hydrogen and the other is hydrogen or a lower alkyl group and n is an integer from 1 to 10 and one of R.sup.3 and R.sup.4 is hydrogen and the other is hydrogen or a lower alkyl group, each of the --(CHR.sup.1 CH.sup.2 O)--units being independently defined, to give a product (C) andstep(2) reacting product (C) with a diisocyanate (D) of formula (II)OCN--R.sup.5 --NCO (II) wherein R.sup.5 is a divalent organic group. Novel succinimides have been prepared by the disclosed process, lubricating oil compositions comprise 1-20% w/w of the modified succinimdes. The succinimides have dispersancy and VI improver properties.
