Compatibilizing effects of the PP-g-SAN copolymer in the PP/clay nanocomposites were investigated by WAXD, TEM, UTM and DMTA. In the study of WAXD pattern of the PP-g-SAN/clay nanocomposite, the d-spacing of the peak was increased. TEM images showed that clay layer was visually broken down and disordered in PP/PP-g-SAN/clay nanocomposites, and WAXD patterns of these nanocomposites displayed a trend in good agreement with that of morphology. From the results of the morphological, thermal, mechanical, and dynamic mechanical studies, it is suggested that the PP-g-SAN copolymer could act as an effective compatibilizer in the PP/clay nanocomposites.
