ABSTRACT:
Hydrocarbon polymers such as ethylene copolymers may be reacted with unsaturated nitrogen-containing monomers or unsaturated carboxylic acids in a synthetic hydrocarbon lubricating oil in the presence of a free radical initiator such as a peroxide. The copolymer grafted directly with the nitrogen-containing monomers may be utilized as an additive for oil compositions, particularly lubricating oil compositions as a V.I.-dispersant additive. The polymer reacted with carboxylic acid may be further reacted with amines or amino-alcohols to also form a multifunctional V.I.-dispersant additive.
