    摘要: A process for the preparation of polymetallooxanes employing inexpensive metal sources such as sand, alumina, and rutile involves dissolving one or more group IIIa, IVa, IVb metaloxy compounds such as metal oxides, metal hydroxides, or hydrates thereof with a di- or polyhydroxyl functional compound in the presence of an amine or alkanolamine. The polymetallooxane products are anionic, neutral, or mixed neutral/anionic moieties, which, when anionic, contain a metallic counterion (cation) or an ammonium or phosphonium ion. Mixed polymetallooxanes, as well as homo polymetallooxanes which may be prepared by the subject process, are suitable for use in preparing coatings, fibers, powders, ceramics, and glasses while being easily processable and economic to manufacture.

    摘要: Inorganic/organic hybrid polymers containing silsesquioxane cages are robust and exhibit desirable physical properties such as strength, hardness, and optical transparency at infrared and ultraviolet wavelengths. The polymers are prepared by polymerizing functionalized polyhedral silsesquioxane monomers such as polyhedral silsesquioxanes bearing two complementarily reactive functional groups bonded to cage silicon atoms by means of spacer moieties. The spacer moieties allow for steric mobility and more complete cure than polyhedral silsesquioxanes bearing reactive functional groups bound directly to cage silicon atoms.

    摘要: Functionalized silsesquioxanes containing from 6 to 24 silicon atoms and minimally about 67 mol percent RSiO3/2 moieties where R is a phenyl group bearing a chemically reactive functional group are highly suitable for use as nanoparticles in producing highly ordered nanocomposites of many types, containing a high proportion of interphase. The nanocomposites have unusual physicochemical properties due to the use of uniform, highly functionalized nanoparticles.
