ETHYLENE COPOLYMER/ETHYLENICALLY UNSATURATED NITROGEN REACTANT ADDUCTS USEFUL AS MULTIFUNCTIONAL V.I. IMPROVERS FOR LUBRICATING OILS

摘要

ABSTRACT OF DISCLOSUREAn ene adduct and adduct derivatives of a C3-C24 ethylenically unsaturatednitrogen-containing reactant, e.g. acrylonitrile, and a copolymer of ethylene,at least one C3 to C50 alpha-monoolefin and at least one non-conjugateddiene, said adduct containing from about 0.005 to 7% by weight nitrogenand having a number average molecular weight of from about 1000 to 500,00,in oil-soluble form have utility as a multi-functional V.I. improver forlubricating oils.
