Abstract: PROBLEM TO BE SOLVED: To use a Mannich base condensation product obtd. by reacting a hydroxyarom. compd. alkylated with a specific ethylene-α-olefin copolymer with an aldehyde reactant and an amine as an oil-soluble lubricant additive exhibiting a high sludge- and varnish-controlling capability and a high lubricant- dispersing capability. SOLUTION: A Mannich base condensation product obtd. by reacting the following three reactants A, B, and C is used as a lubricant-dispersing additive useful in an oil-base compsn.: (A) at least one alkylated hydroxyarom. compd. prepd. by alkylating at least one hydroxyarom. compd. with at least one terminal-unsatd. ethylene-α-olefin copolymer which has a number average mol.wt. of 300-10,000 and of which at least 30% of the polymer chains contain terminal ethenylidene unsaturations; (B) at least one aldehyde; and (C) at least one amine.

Abstract: The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted interpolymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such as amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.
