Abstract: A method for producing aluminum oxide is provided. The method uses an aluminum-oxide-forming agent containing a partially hydrolyzed aluminum alkyl compound containing an aluminum trialkyl or a mixture thereof, and a solvent. It is thus possible to produce an aluminum oxide thin film or aluminum oxide particles on or in a substrate that is not resistant to polar solvents. A method of producing a polyolefin-based polymer nanocomposite containing zinc oxide particles or aluminum oxide particles using a solution containing a partially hydrolyzed zinc alkyl or a solution containing a partially hydrolyzed aluminum alkyl is also provided. The polyolefin-based polymer nanocomposite contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, and does not contain a dispersant. The zinc oxide particles or aluminum oxide particles have an average particle size of less than 100 nm.

Abstract: A method for producing a particulate aluminum alloy involves pulverizing an aluminum alloy in a hydrocarbon solvent in the presence of an organic aluminum compound. Methods for producing trialkylaluminum involve reacting an aluminum-magnesium alloy with an alkyl halide in the presence of a nitrogen-containing organic compound to obtain a trialkylaluminum-containing reaction product, and reacting an aluminum-magnesium alloy and an alkyl halide. A highly active, low viscosity composition containing the particulate aluminum alloy and a method for producing the particulate aluminum alloy-containing composition are also described.
