    Abstract: A lubricant composition having improved viscosity index characteristics is described that comprises (A) at least one vegetable or synthetic triglyceride oil of the formula wherein R , R and R are aliphatic hydrocarbyl groups having at least 60 percent monounsaturated character and containing from about 6 to about 24 carbon atoms and (B) at least one mixed ester of a carboxy-containing interpolymer. Optionally, the composition may also contain (C) a synthetic ester base oil, and (D) an antioxidant. ha

    Abstract: Combinations of substituted carboxylic (especially succinic) acid esters and heterocyclic condensation products of said substituted carboxylic acids are useful in lubricants for inhibitors of "lead paint" deposition in internal combustion engines. Especially useful are compositions comprising a major proportion of a pentaerythritol ester of an alkenyl succinic acid in which the alkenyl group contains at least about 30 carbon atoms, and a minor proportion of a heterocyclic condensation product of said alkenyl succinic acid derived from a 5-membered ring heterocycle containing at least two ring hetero atoms separated by a single carbon atom, at least one of said hetero atoms being nitrogen.

    Abstract: A composition of matter suitable for use as a dispersant-viscosity improver for lubricating oil compositions comprises the reaction product of reactants comprising (a) an oil soluble, substantially hydrogenated, vinyl substituted aromatic-aliphatic conjugated diene block copolymer said copolymer having a number average molecular weight ranging from about 30,000 to about 300,000, grafted with an ethylenically unsaturated carboxylic acid or functional derivative thereof; (b-1) at least one polyester containing at least one condensable hydroxyl group; and (b-2) at least one polyamine having at least one condensable primary or secondary amino group, and optionally, (c) at least one hydrocarbyl substituted carboxylic acid or anhydride.
