    摘要： Processes for preparing aluminoxane comprising: bringing into contact under reaction conditions in an inert atmosphere a liquid containing reaction mixture comprising: (i) a water in oil emulsion comprising water and at least one emulsifier in a first hydrocarbon solvent; and (ii) an organoaluminum compound capable of forming aluminoxane in a second hydrocarbon solvent; provided that the aluminoxane produced by the reaction is present in solution under the reaction conditions. In a preferred embodiment a support carrier for the aluminoxane: (i) is present during the contact step or (ii) is introduced following contact. A polymerization catalyst can be prepared wherein the support carrier is SiO2 and a Group 3 to Group 10 metal containing single site complex is mixed with the aluminoxane. Catalysts suitable for polymerizing an olefin such as ethylene or copolymerizing an olefin with at least one C3 to C20 alpha-olefin can be produced.

    摘要： Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties. The method of adherence to the target yarn, fiber, and/or fabric may be performed any number of ways, most preferably through the utilization of a jet dyeing system or through a steam-transfer method. The particular methods of adherence, as well as the treated textile fabrics and individual fibers are also encompassed within this invention.

    摘要： A method cleaning up internal components of a fuel injector for a diesel engine. The method includes operating a fuel injected diesel engine on a fuel composition that includes a major amount of diesel fuel and from about 5 to about 500 ppm by weight of a reaction product derived from (a) a hydrocarbyl substituted dicarboxylic acid, anhydride, or ester and (b) an amine compound or salt thereof of the formula wherein R is selected from the group consisting of hydrogen and a hydrocarbyl group containing from about 1 to about 15 carbon atoms, and R1 is selected from the group consisting of hydrogen and a hydrocarbyl group containing from about 1 to about 20 carbon atoms. The reaction product is characterized by a particular FTIR spectrum.

    摘要： A fuel composition for a fuel injected internal combustion engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a fuel-injected internal combustion engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt of a hydrocarbyl amine and a hydrocarbyl-substituted alkyl-hydroxybenzoate. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the fuel injected internal combustion engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt. The hydrocarbyl-substituted alkyl-hydroxybenzoate contains one or more hydrocarbyl substituents providing a total of at least 8 up to about 200 carbon atoms, provided the one or more hydrocarbyl substituents do not contain sulfur, oxygen, or nitrogen atoms.
