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.
