Abstract(s)A modified PP and an organoclay (Cloisite C15A, a montmorillonite modified with alkyl ammonium) were incorporated in a PA/PP 70/30 w/w blend by means of twin-screw melt compounding. The dispersion of the nanoclay into the polymer matrix and its eventual compatibilization effect were investigated by collecting samples along the barrel and characterizing them by X-ray diffraction (XRD), oscillatory rheometry, scanning and transmission microscopy (SEM and TEM). Chemical and morphological changes occurred mostly during polymer melting. The morphologies of the nanocomposite and of the compatibilized blends were much finer than that of the physical blend. When both the modified PP and the organoclay were present the morphology was even finer, suggesting that the organoclays may produce a compatibilization effect similar to that of PP-g-MA.
