    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 2 and C 4 to C 10 olefins. The unsaturated acidic reactant comprises at least one unsaturated C 4 to C 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： The amount of nitrogen oxide (NOx) and hydrocarbon emissions emanating via the exhaust during operation of a gasoline engine is reduced by dispensing to a gasoline engine adjusted to operate primarily at an air-to-fuel ratio between lambda of about 0.9 to about 1.15, a gasoline that contains a minor amount of (i) a cyclopentadienyl manganese tricarbonyl compound and (ii) an alkyllead antiknock agent. Components (i) and (ii) are proportioned such that there is dissolved in the fuel a substantially equal weight of manganese as (i) and lead as (ii), and the amount of (i) and (ii) used in the fuel is an amount that reduces the amount of NOx and hydrocarbons in the engine exhaust on combustion of the fuel with an air-to-fuel ratio between lambda of about 0.9 to about 1.15. Lambda is the actual air-to-fuel ratio divided by the stoichiometric air-to-fuel ratio. The stoichiometric air-to-fuel ratio is a lambda value of one.

    摘要： Organic silicon compounds such as tetraloweralkylorthosilicates, silicon tetracarboxylates, and silicon-containing reaction products derived from carbohydrates, such as glucose, sucrose, and ascorbic acid are useful in treating, preventing, or delaying the onset of bone disease in warm blooded vertebrates, including man and domesticated animals of economic importance, such as poultry, house pets, and horses, cattle, swine, and sheep.
