Abstract
C5 -C9 lactone based adduct materials are made by reacting a C5 -C9 lactone with a polyamine, a polyol or an amino alcohol to form a lactone adduct intermediate, and thereafter reacting the intermediate with a hydrocarbyl substituted C4 -C10 monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl succinimide, which, in turn, preferably was made by reacting a polymer of a C2 to C10 monoolefin, preferably polyisobutylene, having a molecular weight of about 300 to 10,000 with a C4 to C10 monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are 0.7 to 2.0 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adduct material are useful per se, as oil soluble dispersant additives, and are useful in fuel and lubricating oil compositions including concentrates containing the additives.
