Abstract: The present invention is directed to an oil-soluble fuel and lubricating oil additive comprising at least one terminally unsaturated ethylene alpha-olefin polymer 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 polymers 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 fuel and lubricating oil additives, e.g., as dispersants.

Abstract: Compositions are disclosed for improving at least the low temperature flow properties of lubricating oils. The compositions are dual additives including a first component which is a polymer or interpolymer of a C14 carboxylate, such as a C14-dialkyl fumarate/vinyl acetate interpolymer, and a second component which is a lubricating oil flow improver comprising a non-ethylene containing polymer or interpolymer such as dialkyl fumarate/vinyl acetate interpolymer, esterified styrene/maleic anhydride interpolymer, or esterified olefin/maleic anhydride interpolymer.
