ABSTRACT:
Ethylene/C.sub.3-12 .alpha.-monoolefin copolymers having an average molecular weight of about 10,000-1,000,000 containing about 1-10 pendent amide and/or ester groups per each 10,000 molecular weight are effective ashless dispersants and impart viscosity lift to lubricating oils. They are made by the permanganate oxidation of ethylene/C.sub.3-12 .alpha.-monoolefin
on-conjugated diene terpolymers which oxidizes the residual olefinic double bond of the diene unit to a carboxylic acid which is amidated and/or esterified.
