  • Patent number: 7368496
    Abstract: A nanocomposite composition having superior barrier properties and an article comprising the same are provided. The nanocomposite composition includes: a polyolefin resin; a nanocomposite having barrier properties, and including intercalated clay and one or more resins having barrier properties, and a compatibilizer. The resin having barrier properties comprises an ethylene-vinyl alcohol copolymer, a polyamide, an ionomer, a polyvinyl alcohol, or a combination comprising one or more of the foregoing resins. The nanocomposite composition has superior mechanical strength and can form a strong barrier to oxygen, organic solvent, and moisture. Also, the nanocomposite composition has superior chemical barrier properties and can be used in single/multi-layer blow molding and film processing.

  • Patent number: 7138452
    Abstract: The present invention relates to a nanocomposite blend composition having superior barrier properties, and more particularly to a nanocomposite blend composition comprising a polyolefin resin; one or more nanocomposites having barrier properties, selected from an ethylene-vinyl alcohol (EVOH)/intercalated clay nanocomposite, a polyamide/intercalated clay nanocomposite, an ionomer/intercalated clay nanocomposite, and a polyvinyl alcohol (PVA)/intercalated clay nanocomposite; and a compatibilizer. This nanocomposite blend composition has superior mechanical strength and superior barrier properties to oxygen, organic solvent, and moisture. Also, it has superior chemical barrier properties and is applicable to single/multi-layer blow molding and film processing.
