  • Patent number: 7811659
    Abstract: The invention relates to a high optical purity toughened copolymer film or coating. The copolymer is a graft or block copolymer, preferably acrylic, preferably produced by a controlled radical polymerization having an extremely low degree of particulate contamination and excellent optical properties. The film or coating is preferably formed by solvent-casting on a temporary substrate or solvent-coating on a permanent substrate.
    Type: Grant

  • Patent number: 5276547
    Abstract: An electrochromic element useful in an electrochromic glass or mirror device and a process for making such element. The element is a five-layered structure including an electrolyte ion conducting layer interposed between first and second inorganic electrochromic layers which are interposed between a pair of conductive electrodes. The first and second inorganic electrochromic layers are different and are capable of exhibiting color-forming properties complementary to one another upon the incorporation of an alkali metal or Ag ion, a mixture of alkali metal or Ag ions or a mixture of alkali metal or Ag and hydrogen ions. The electrolyte ion conducting layer may be a copolymer of ethylene oxide, butylene oxide or methyl glycidyl ether, and optionally a small amount of allyl glycidyl ether, along with an ionizable salt, or may be a polyurethane gel formed by reacting the copolymer with triisocyanate, along with an ionizable salt.

  • Patent number: 5102691
    Abstract: A method for producing coatings on a heated substrate, preferably glass, comprises pretreating the substrate with a gaseous composition of water, air and a fluorine compound, and thereafter depositing a fluorine-doped tin-oxide coating on the substrate.
