Abstract

Poly (C₅ -C₉ lactone) modified Mannich base adducts are made by reacting a C₅ -C₉ lactone, an amine, an aldehyde, an N-hydroxyarylamine, and a hydrocarbyl substituted C₄ -C₁₀ monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl, succinic anhydride, which, in turn, preferably is made by reacting a polymer of a C₂ to C₁₀ monoolefin, preferably polyisobutylene, having a molecular weight of about 700 to 10,000 with a C₄ to C₁₀ monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are about 0.7 to 2.00 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adducts are useful per se as oil soluble dispersant additives. They are also useful in fuel and lubricating oil compositions, as well as in concentrates and additive packages.
