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 extractible salts of organic cations. This invention is also derected to processes for preparing polymer-clay nanocomposites, intercalates, exfoliates, and articles or products produced from nanocomposite materials.
