Abstract:
The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.
