  • Patent number: 5693418
    Abstract: Disclosed is a laminated film or sheet comprising poly-4-methyl-1-pentene laminated on a paper layer. By using poly-4-methyl-1-pentene having a low melting point, formation of cracks and other defects in the resin layer is prevented and the oil and fat impermeability is improved. If an intermediate layer of a specific polymer is formed in addition to the poly-4-methyl-1-pentene layer, the oil and fat impermeability is further improved. A box-shaped vessel (carton) and a release paper for an artificial leather can be prepared from this laminated film or sheet.

  • Patent number: 5686162
    Abstract: Electronic devices protected by an organic polymeric encapsulant and placed in a corrosive environment can have added protection by dispersing in the encapsulant particles of a solid buffer which tend to neutralize the effect of the corrosive agent. This approach is quite effective when strong acids are the corrosive agents, and when solid acid-base buffers are dispersed in the polymeric material. The encapsulant may be elastomeric, and silicone elastomers containing solid acid-base buffers are quite effective in protecting the underlying electronic device from corrosion by strong acids.
