  • Patent number: 7714095
    Abstract: Polyether polymers, such as polyetherimides, are prepared by the reaction of a dihydroxy-substituted aromatic hydrocarbon alkali metal salt, such as bisphenol A disodium salt, with a bis(N-(chlorophthalimido))aromatic compound, such as 1,3- and/or 1,4-bis(N-(4-chlorophthalimido))benzene, in a solvent such as o-dichlorobenzene and in the presence of a phase transfer catalyst such as a hexaalkylguanidinium chloride. Several embodiments may be employed to improve the method. They comprise employing substantially dry reagents, employing a high solids level in solvent, beginning with an excess of bis(N-(chlorophthalimido))-aromatic compound and incrementally adding alkali metal salt, employing alkali metal salt of small particle size, and using reagents of high purity.

  • Publication number: 20040022937
    Abstract: A method of forming a plurality of monodisperse nanoparticles. Each of the nanoparticles comprises a nanocrystalline inorganic core and at least one outer coating comprising an ionizable stabilizing material that substantially covers the core. The method comprises the steps of: combining a nonpolar aprotic organic solvent, an oxidant, and a first surfactant; providing at least one organometallic compound to the combined nonpolar aprotic organic solvent, oxidant, and first surfactant; and heating the combined nonpolar aprotic organic solvent, oxidant, first surfactant, and the at least one organometallic compound under an inert gas atmosphere to a first temperature in a range from about 30° C. to about 400° C.
