  • Patent number: 7476712
    Abstract: The invention is directed to a film which comprises a poly(carboxylic acid) polymer and a polyvalent metal compound, which is endowed with excellent gas barrier property against, for example oxygen, which has such resistance that the appearance, shape, and gas-barrier properties are not impaired by neutral water, high-temperature water vapor, or hot water; a laminate produced by use of the film; and a process for producing the film or laminate industrially conveniently at low cost. The film or laminate of the present invention is suitable for use as a package, packaging container, or vacuum insulation material for articles which are apt to be deteriorated by oxygen, etc., such as foods, beverages, chemicals, medicines, and metallic precision parts; e.g., electronic parts.

  • Patent number: 7030194
    Abstract: To eliminate a halogen group of a halogen group-terminated vinyl polymer, the present invention provides a method to treat said polymer with an oxy anion compound to thereby eliminate a terminal halogen group easily. Thus, it is possible to improve the storage stability of the polymer or a curable composition comprising said polymer and to prevent various materials coming into contact with the reaction apparatus or the polymer from being corroded. In particular, it is possible to improve the storage stability of a crosslinkable silyl group-containing polymer.
