Ethylene copolymer/ethylenically unsaturated nitrogen reactant ene adducts having utility as multifunctional V. I. improvers for lubricating oils

摘要

An ene adduct and adduct derivatives of a C.sub.3 -C.sub.24 ethylenically unsaturated nitrogen-containing reactant, e.g. acrylonitrile, and a copolymer of ethylene, at least one C.sub.3 to C.sub. 50 alpha-monoolefin and at least one non-conjugated diene, said adduct containing from about 0.005 to 7% by weight nitrogen and having a number average molecular weight of from about 1000 to 500,000, in oil-soluble form have utility as a multi-functional V.I. improver for lubricating oils.
