Hydrocarbyl substituted C4 to C10 monounsat- urated dicarboxylic acid, anhydrides or esters, e.g. poly- isobutenyl succinic anhydride, preferably made by reacting polymer of C2 to C10 monoolefin, preferably polyisobuty- lene, having a molecular weight of about 700 to 1200, preferably with a C4 to C10 monounsaturated acid, anhydr- ide or ester, preferably maleic anhydride, such that there are 1.2 to 2.0 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mix- ture. The resulting materials may be further reacted with amines, alcohols, amino alcohols, boric acid, etc. to form dispersants.
