  • Patent number: 5190698
    Abstract: There is disclosed a composite of 1) a polymer containing repeating units derived from a vinyl carboxylic ester having at least one organo terminated poly(alkylene oxide) side chain with the proviso that the poly(alkylene oxide) is present in an amount greater than 35 mole percent of the total of all backbone monomer units and alkylene oxide units in the polymer and 2) a metal oxide wherein the metal oxide comprises between about 1 and about 60 percent by weight of the composite. The composites can be made by a process comprising the steps of:combining the described polymer and a metal oxide precursor in a solvent solution;casting or coating the resulting solution onto a substrate;curing the resulting sample to form a composite of the polymer and the metal oxide.Optionally, the composite can be removed from the substrate to form a transparent free standing film.

  • Patent number: 5190819
    Abstract: The invention provides fibers formed of a blend of metal oxide, such as titanium or zirconium oxide, with etheric phosphazene. The invention optionally contains salt for antistatic fibers. The composition of the invention is formed by preparing solutions of etheric phosphazene and inorganic alkoxides, such as titanium isopropoxide. The solutions are then formed into fibers and cured at room temperature or with moderate heating. Fibers produced can be extensible, tough, hard, flexible, or brittle. They are multicomponent blends of the titaninum or zirconium oxide and phosphazene. The composite may be doped with low lattice energy salts to form conductive fibers.
