1. A C5 -C9 lactone adduct material useful as an oil additive and formed by first reacting at a temperature of from about 100 to about 250°

  • C. for a period of from about 1 to about 10 hours a hydrocarbyl substituted C4 -C10 dicarboxylic acid producing material (I) with the reaction product (II) of a C5 -C9 lactone with a member selected from the group consisting of (a) a polyamine having from about 2 to 60 total carbon atoms and from about 2 to about 12 nitrogen atoms, (b) an aliphatic polyhydric alcohol containing up to about 100 carbon atoms and from about 2 to about 10 10 hydroxyl groups, (c) an amino alcohol containing up to about 50 total carbon atoms, from 1 to about 3 nitrogen atoms and from 1 to about 15 hydroxyl groups, or (d) mixtures thereof, and then post-treating the reaction product of (I) and (II) with a boron compound;

    said reaction product (II) being prepared at a temperature of from about 30 to about 200°

    C. when said C5 -C9 lactone is reacted with said polyamine and at a temperature of about 50 to about 200°

    C. when said C5 -C9 lactone is reacted with said aliphatic polyhydric alcohol or with said amino alcohol, said hydrocarbyl substituted acid producing material being formed by reacting an olefin polymer of a C2 -C10 monoolefin having a number average molecular weight of about 300 to about 10,000 and a C4 -C10 monousaturated dicarboxylic acid material selected from the group consisting of acids, esters and anhydrides and containing an average of from about 0.7 to about 2.0 moles of dicarboxylic acid producing material per mole of said olefin polymer used in the reaction, said adduct having, on the average, a degree of polymerization of C5 -C9 lactone of less than about 100.
