    摘要: A novel copolymer of an unsaturated acidic reactant and an atactic vinyl terminated propene polymer (VTPP) and its use in preparation of fuel and lubricant additives is taught. The VTPP has a major amount of polymer chains containing terminal vinyl unsaturation, a number average molecular weight of at least 500, and comprises at least 70 weight per cent propene and 0 to 30 weight per cent of at least one olefin selected from the group consisting of C.sub.2 and C.sub.4 to C.sub.10 olefins. The unsaturated acidic reactant comprises at least one unsaturated C.sub.4 to C.sub.10 carboxylic or dicarboxylic acid or anhydride. An oil soluble dispersant additive of the invention useful in oleaginous compositions is prepared by contacting the atactic VTPP copolymer with at least one nucleophilic reagent selected from the group consisting of amines, alcohols, metal reactants and mixtures thereof under conditions effective to form adducts of the nucleophilic reagent with the copolymer. The novel dispersants made from the copolymers and terpolymers of the invention can be polymeric succinic ester-amide dispersants, polymeric succinimide dispersants, polymeric succinic amide-triazole dispersants, or polymeric succinic triazole dispersants. Fuel and lubricant compositions containing such additives are a part of the invention.

    摘要: A method, composition and filter for reducing the presence of sludge or varnish precursors in a lubricating oil circulating within an internal combustion engine. The lubricating oil containing sludge or varnish precursors is contacted with discrete particles of an oil insoluble, oil wettable compound having an antioxidant functional group and/or a dispersant functional group, which are capable of complexing with sludge or varnish precursors. Preferably the compounds comprises a crosslinked amine having ethylene amine functionality. The starting polyethylene amines have a number average molecular weight in the range of about 100 to about 60,000, preferably 200 to 250 and are crosslinked with a silicon oxide, silane, silicate, epoxide, quinone, or phenol-formaldehyde crosslinking agent. The particles are encaged within a one or two stage oil filter together with filtering media such as chemically active filter media, physically active filter media and inactive filter media.
