    摘要: A container, such as a metered dose inhaler, suitable for use with a propellant-based medicinal formulation, the container comprising one or more treated metal surfaces that come into contact with the medicinal formulation, wherein the one or more treated metal surfaces are characterized by an organic surface treatment compound covalently bonded to the metal surface through a reactive head group selected from either phosphonic acid or carboxylic acid and wherein the organic surface treatment compound is further characterized by an exposed, substantially non-reactive tail group disposed away from the metal surface. Also, metered dose inhaler canisters and valves with treated surfaces.

    摘要: This invention relates to antisoiling compositions for antireflective substrates. More particularly, this invention relates to methods for depositing antisoiling compositions onto antireflective substrates. In particular, this invention relates to a method of depositing an antisoiling composition on an antireflective substrate comprising vaporizing an antisoiling composition and depositing the antisoiling composition onto an antireflective substrate. In another aspect, this invention relates to method of preparing an antireflective film stack comprising depositing an antireflective layer onto the surface of a transparent substrate and vapor depositing an antisoiling layer onto the surface of the antireflective layer. In yet another aspect, this invention relates to a method of depositing an antisoiling composition on an antireflective coated ophthalmic lens comprising vaporizing an antisoiling composition and depositing the antisoiling composition onto an antireflective coated ophthalmic lens.

    摘要: Normally liquid peroxidic poly(perfluorooxyalkylene) compositions comprising a mixture of peroxidic poly(perfluorooxyalkylene) compounds, derivatives of the poly(perfluorooxyalkylene) compositions comprising a mixture of non-peroxidic polyfluoropolyether compounds, and derivatives of the polyfluoropolyether compositions comprising functional and non-functional derivatives of the polyfluoropolyether compositions are provided. Each peroxidic poly(perfluorooxyalkylene) compound comprises a backbone of randomly distributed perfluorooxyalkylene units, represented by the formulas ##STR1## which when bonded to an --O-- of any of the perfluorooxyalkylene units, forms a peroxy group, --O--O--, which imparts the peroxidic characteristics to the material, and backbone-pendant perfluoroalkoxy groups or perfluoroalkoxy groups substituted with one or more ether oxygen atoms, the terminal ether oxygen atoms of which are bonded to carbon atoms of the ##STR2## backbone units.
