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.

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.

A method of compatibilization asphaltenes containing bituminous liquids which process comprises: a) reacting an asphaltene with phosphorous trichloride in the presence of a liquid to form a phosphochlorinated asphaltene containing from about 0. 01 wt % to about 20 wt. % phosphorous; b) reacting the phosphochlorinated asphaltene with an equimolar amount of aliphatic or aromatic alcohols and phenols selected from the group consisting of: i) an aliphatic alcohol; ii) a naphthyl alcohol; iii) an alkyl quinizarin; iv) an oligomeric mixed polyether aliphatic terminal diol; and v) an oligomeric polyalkene terminal diol to produce a compatibilized asphaltene; and c) recovering the compatibilized asphaltene product.

A polymeric lubricant additive that behaves as a viscosity index improver and imparts enhanced anti-oxidancy, dispersancy, and anti-wear properties to said lubricant oil has been prepared. The polymeric substrate is a random co- or terpolymer of ethylene propylene and a third monomer; or a block terpolymer of styrene--ethylenebutylene--styrene where hydrogenation has removed aliphatic unsaturation. Ethylenically unsaturated carboxylic acid or acid anhydride is grafted to these aforementioned substrates and imidized with amino-thiadiazole of the formula: ##STR1## wherein R. sub. 1 is H. sub. 2 or a (C. sub. 1 -C. sub. 10) alkyl radical selected from the group consisting of a alkyl, alkenyl, alkoxyl, aralkyl, alkaryl, hydroxyalkyl and aminoalkyl, to produce said polymeric lubricant additive.
