Polypropylene/poly(ethylene terephthalate) blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by injection molding. The MMT dispersion was evaluated by X-ray diffraction and transmission electron microscopy. The results showed a better dispersion of the MMT when maleic anhydride grafted polypropylene (PP-MA) was used. The clay was preferentially situated in...
PET nanocomposites were prepared using montmorillonite with different organic modifiers (Cloisite ® 15A, 30B and 10A). TEM, WAXD and DSC were used for the characterization. Nanocomposites of intercalated and exfoliated morphologies were obtained, and an average maximum distance between the platelets was observed in the intercalated morphology. The clay nucleated the PET crystallization process,...
