Abstract:
A polymeric lubricant additive that behaves as a viscosity index improver and imparts enhanced anti-oxidancy, dispersnacy, and anti-wear properties to said lubricant oil has been prepared. The polymeric substrate is a random co- or terpolyer of ethylene propylene and a third monomer onto which an ethylenically unsaturated carboxylic acid or acid anhydride has been grafted. The polymer is imidized with aminoheterocyclics and hydroxylalkylated using an aldehyde or ketone an alkylation; than alkylated using mercaptoheterocyclics.

Abstract:
A polymeric additive prepared from ethylene and at least one (C.sub.3 -C.sub.10) alpha-monoolefin and a non-conjugated dienes or triene comprising from about 15 to 80 mole percent of ethylene and from about 20 to 85 mole percent of the (C.sub.3 -C.sub.10) alpha-monoolefin and from about 0 to 15 mole percent of the diene or triene. This polymeric substrate has a number average molecular weight ranging from about 5,000 to about 500,000. It is modified by reacting the polymer with an unsaturated epoxide wherein the intermediate graft co- or terpolymer is characterized as having pendant epoxides within the substrate.Post-reacting this graft co- or terpolymer with 1,3,4-thiadiazine modified with substituted phenols, diaryl amines, or phenophiazines generates a polymeric lubricant additive with enhanced anti-oxidant, dispersant, and anti-wear properties.
