One-pot preparation of polymer/clay nanocomposites starting from Na+ montmorillonite.: 1.: Melt intercalation of ethylene-vinyl acetate copolymer

The same intercalated structure, as determined by X-ray diffraction, is obtained whether EVA-based nanocomposites are prepared starting from an organo-modified montmorillonite (compound 1) or from a Na+ montmorillonite compatibilized by reactive processing using an alkylammonium bromide (compound 3) equivalent to the clay modifier of compound 1.
