    摘要： A process for producing a dispersant/VI improver for use in finished lubricating oil compositions comprises eacting in a normally liquid substantially inert organic solvent

    (a) a copolymer of an olefin and a monomer having the structure:-
    wherein X and X' are the same or different provided that at least one of X and X 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.
