A polymer/clay nanocomposite having improved gas barrier comprising a clay material with a mixture of two or more organic cations and a process for preparing same

摘要

This invention relates to a polymer-clay nanocomposite having an improved gas permeability comprising (i) a melt-processible matrix polymer, and incorporated therein (ii) a layered clay material intercalated with a mixture of at least two organic cations. The invention also relates to processes for preparing a nanocomposite and articles produced from a nanocomposite.
