APPROACH TO TOUGHEN POLYPROPYLENE PROCESSED BY PLANE COMPRESSION
An approach which formed sheet structure through plane compression processing in the bulk of polypropylene (PP) polymer was suggested and the mechanism was presented based on a series of experiment. The variety of super-molecular structure that the spherulite deformed into ellipse even fractures piece in the pressure field helped to increase the impact resistance and changed the thermo performance. In the polar reign of spherulite, the lamellae underwent a slight deformation, and the lamellae broke into fraction and then slid each other along the flow direction in the equatorial region. Finally, the lamellae in the sample aligned along the flow direction, and the sheet structure which was packed each other by lamellae was built up by plane compression processing.
