Abstract: The present invention provides an oil-dispersible composite of metallic nanoparticles and a method for synthesizing the same. The composite primarily includes metallic nanoparticles and an oily polymeric polymer such as polyurethane (PU). The oily polymeric polymer serves as a carrier of the metallic nanoparticles by chelating therewith so that the metallic nanoparticles are dispersed uniformly. In the method of the present invention, the metallic ions are first chelated by the oily polymeric polymer and then reduced into nanoparticles. The composite of the present invention is about 5 to 100 nm in particle size.

Abstract: A thermoplastic polymer composition that employs a flame retardant formed from a phosphinic compound and organometallic phosphoric compound is provided. The present inventor has discovered that the organometallic phosphoric compound can counteract the tendency of the phosphinic compound to degrade the mechanical properties of the composition when used at certain concentrations. Furthermore, the present inventor has also surprisingly discovered that the organometallic phosphoric compound may itself act as a flame retardant and thus contribute to the overall flammability performance of the composition. Among other things, this allows compositions to be formed with a lower phosphinic content with the same flammability performance.
