Abstract
C5 -C9 lactone derived materials are made by simultaneously reacting (a) a C5 -C9 lactone with (b) a polyamine, a polyol or an amino alcohol and (c) a hydrocarbyl substituted C4 -C10 monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl succinimide, which 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 lactone derived materials, which may be post-treated, for example, with a boron compound, are useful, per se, as oil soluble dispersant additives, and are useful in fuel and lubricating oil compositions including concentrates containing the additives.
