中文摘要	crystallization behavior of sheared polymer melts of a series of poly(ethylene-co-octene)s with different octene content was investigated by different scanning calorimetry (dsc), wide angle x-ray diffraction (waxd) and synchrotron small-angle x-ray scattering (sr-saxs) techniques. the dsc results indicated that the hexyl branches content had dramatic effects on the thermal properties and crystallinity of polyethylene. it was also found that shear had no obvious effects on the size of either crystallite or lamellae. however, both crystallite and lamellae were oriented by shearing, especially for the lamellae. all obtained results indicate that the initial states of the polymer melt play an important role in affecting the crystallization behaviors. the difference of the shear-induced crystalline structure evolution and the orientation between crystallite and lamellae support the preordered mesomorphic phase of flexible polymer crystallization process proposed by strobl.
