摘要
The polypropylene wax modified by ultraviolet irradiation. The polypropylene-montmorillonite nanocomposiles were prepared by direct melting intercalation oj polypropylene powders. The structure of polypropylene , the polyproprlene irradiated, montmorillinote and polypropylene-montmorillonite composites were studied by XRD, 1R 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 ( d0.01) of montmorillonite increases, and the melt absorption peak of polypropylene in layer is eliminated.
