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