    摘要： 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.
