Abstract: Lubricant additives exhibiting dispersant and viscosity-index (V.I.) improving properties are obtained by the amination of oxidized high molecular weight amorphous copolymers of essentially ethylene and propylene having a number average molecular weight of from about 1,500 to about 200,000 or more, and at least about 150 pendant methyl groups per 1,000 chain carbon atoms, with a primary or secondary aliphatic amine or polyamine, said reactants being employed in the molar ratio of from about 1:2 to about 1:20, respectively; the aminated oxidized copolymers having a number average molecular weight in the range of from about 1,500 to about 20,000 exhibit excellent dispersancy properties, while those having a number average molecular weight of at least about 20,000 exhibit bi-functional dispersancy and V.I. improving properties.
