摘要：

Polypropylene/montmorillonite (PP/MMT) nanocomposites were prepared via intercalative Polymerization. The wide angle X-ray diffractometer (WAXD) patterns and the transmission electron microscope(TEM) images of the PP/MMT nanocomposites showed the MMT layers were exfoliated into nanometer size and dispersed uniformly in the PP matrix. The nanocomposites exhibited much higher storage modulus compared to that of pure PP. Especially at the temperature higher than T-g, the storage modulus of PP/clay nanocomposites was about three times that of pure PP. The maximum decomposition temperature and HDT of the nanocomposites remarkably increased with the increasing of MMT content.
