Abstract: The invetion is directed to a polymer-clay nanocomposite material comprising a melt-processible matrix oplymer and a layered clay material having decreased levels of extractable material, such as extratible saltssof organic cations. This invention is also derected to processes for preparing polymer-clay nanocomposites, intercalates, exfoliates, and articles or products produced from nanocomposite materials.

Abstract: The invention is directed to a polymer-clay nanocomposite material comprising a melt-processible matrix polymer and a layered clay material having low quartz content. This invention is also directed to a process for preparing a polymer-clay nanocomposites, and articles or products produced from nanocomposite materials.

Abstract: This invention relates to novel multilayer formed articles including, but not limited to containers such as bottles, tubes, pipes, preforms and films (including oriented films such as biaxially oriented) comprising a melt processible resin having dispersed therein a platelet filler. The multilayer formed articles have improved barrier while maintaining excellent clarity. More particularly, the multilayer structures of the present invention display haze values of less than about 2% and carrier resins which are substantially free from platelet particles having a diameter greater than about 15 microns.
