    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: Foamable compositions comprise (a) at least one normally liquid, unsaturated perfluorochemical blowing agent compound selected from the group consisting of perfluoroolefin compounds, e.g., perfluoro(4-methylpent-2-ene), perfluoroaromatic compounds, e.g., hexafluorobenzene, and perfluorocycloolefin compounds, e.g., perfluorocyclohexene, the perfluoroolefin compounds optionally containing one or more catenary heteroatoms; and (b) at least one foamable polymer or the precursors of at least one foamable polymer. The compositions are useful in preparing polymeric, e.g., polyurethane, foams.
