ABSTRACT:
The present invention is directed to a viscosity index improver for lubricating oil compositions comprising the reaction product of A a copolymer of ethylene and at least one other alpha-olefin monomer, said copolymer grafted with ethylenically monoansaturataed carboxylic acid material and B amido-amine or thioamido-amine comprising the reaction product of a polyamine and alpha, beta-unsaturated compound of the formula ##STR1## wherein X is oxygen or sulfur, Y is OR.sup.4, --SR.sup.4 or ##STR2## and R.sup.1, R.sup.2, R.sup.3 R.sup.4 and R.sup.5 are independently selected from hydrogen, hydrocarbyl and substituted hydrocarbyl.
