    摘要: A copolymer including ethylene units and units of one or more C3-10 alpha-olefins. The copolymer has a number average molecular weight of less than 5,000 g/mol, as measured by GPC. The ethylene unit content of the copolymer is less than 80 mol %. 70 mol % or greater of the copolymer has a carbon-carbon double bond in a terminal monomer unit, and at least 70 mol % of the terminal unsaturation is vinylidene, one or more tri-substituted isomers of the vinylidene or any combination thereof. The copolymer has a crossover temperature of −20° C. or lower and/or a certain average ethylene run length. Also disclosed are a method for making the copolymer and polyolefins plasticized with 1-40 wt. % of the copolymer. The copolymers may low metal (ash) and/or fluorine contents.

    摘要: A fuel composition including a fuel and a fuel additive including a fuel soluble detergent selected from succinimide compounds of the Formula (I), Mannich detergents of the formulae (IIa), and amine detergents of the formulae (IIIa) and (IIIb). The fuel soluble detergents are derived from a specific class of ethylene-alpha olefin copolymers having an Mn of less than 5,000 g/mol, an ethylene unit content of more than 40 mol % to less than 90 mol %; a terminal unsaturation of 70 mol % or greater; at least 70 mol % of the unsaturation is terminal vinylidene, one or more tri-substituted isomers of the terminal vinylidene or any combination thereof, an average ethylene run length of less than 2.6; and wherein nC2,Actual>nC2,Statistical. Methods employing the fuel compositions for operating diesel and gasoline engines to reduce injector valve deposits, valve sticking and injector nozzle fouling, and a method for stabilizing a diesel fuel composition.

    摘要: A copolymer including ethylene units and units of one or more C3-10 alpha-olefins. The copolymer has a number average molecular weight of less than 5,000 g/mol, as measured by GPC. The ethylene content of the copolymer is less than 80 mol %. At least 70% of molecules of the copolymer have an unsaturated group, and at least 70% of said unsaturated groups are located in a terminal vinylidene group or a tri-substituted isomer of a terminal vinylidene group. The copolymer has a crossover temperature of −20° C. or lower and/or a certain ethylene run length. Also disclosed are a method for making the copolymer and polyolefins plasticized with 1-40 wt % of the copolymer.

    摘要: Engine oil \s and methods for use in soot-producing engines. The engine oil contains a major amount of a base oil and a dispersant reaction product of A) a hydrocarbyl-dicarboxylic acid or anhydride, and B) at least one polyamine, that is post-treated with C) an aromatic carboxylic acid, an aromatic polycarboxylic acid, or an aromatic anhydride, wherein all carboxylic acid or anhydride groups of C) are attached directly to an aromatic ring. A molar ratio of carboxyl groups from components A) and C) to nitrogen atoms from component B) of from 0.9 to 1.3 is used to make the dispersant which also has a molar ratio of component C) to component B) of at least 0.4 and when component B) has an average of 4-6 nitrogen atoms per molecule, a molar ratio of A) to B) is from 1.0 to 1.6.
