AbstractPolypropylene/montmorillonite (PP-MMT) nanocomposites were synthesized via intercalative polymerization. The morphology evolution and microstructure of the nanocomposites were investigated by means of polarized optical microscopy TOM), scanning electron microscopy (SEM), transmission electron microscopy(TEM) and wide angle X ray diffraction (WAXD). It has been found that the big primary MMT particles were mostly dissociated into smaller secondary particles, which consists of 2similar to20 individual MMT layers and expanded gallery distance full of PP chains. The morphology evolution model of the PP-MMT during the intercalation polymerization is discussed. It has been also found that the presence of MMT influences the spherulite morphology of the polypropylene in the PP-MMT nanocomposites with increasing of MMT content in nanocomposite, the dimension of the spherulite reduced and the shape became distorted.
