SMECTITE CLAY/ORGANIC CHEMICAL/POLYMER COMPOSITIONS USEFUL AS NANOCOMPOSITES

摘要

This invention is of a composition comprised of a smectite clay modified with an organic chemical composition and a polymer. The composition consists of an organic chemical/smectite clay intercalate that has been ion-exchanged and reacted and intercalated with one or more quarternary ammonium compounds and an anionic material and further blended into a polymer resin to make a nanocomposite composition. This material can be blended into a wide variety of polymers. This kind of system gives improved dispersion over conventional organoclays, intercalates or hybrid clays described in the literature, especially in non-polar resins. The defined organoclay has been found to be highly dispersible in a variety of polymers, whether polar or non-polar.
