%X In order to study the crystal structure of polypropylene obtained by cooling melt near melting point under shear flow,samples were prepared by using a dynamic packing injection molding (DPIM) device which was designed by ourselves. With the aid of scanning electron microscopy ( SEM ),differential scanning calorimetry (DSC) and wide-angle x-ray diffraction (WAXD),crystal stuctures and morphologies were studied from skin to shear regions in these samples obtained by cooling melt near melting point under shear...
