Abstract

The polypropylene was modified by ultraviolet irradiation. The polypropylene-montmorillonite nanocomposites were prepared by direct melting intercalation of polypropylene powders. The structure of polypropylene, the polyproprlene irradiated, montmorillinote and polypropylene-montmorillonite composites were studied by XRD, IR and DSC. The results show that the PP molecules can are oxidized during ultraviolet irradiation, melt polypropylene can intercalate into montmorillonite layer. As a result, the layered distance (d001) of montmorillonite increases, and the melt absorption peak of polypropylene in layer is eliminated.
