| 中文摘要 | the final structure of molten syndiotactic polypropylene (spp) sheared under different conditions was investigated by synchrotron small-angle x-ray scattering (saxs) and wide-angle x-ray diffraction (waxd) techniques to elucidate the shear effects on spp crystalline structure. the results obtained from the waxd show that there is no variation on crystalline form but a little difference on the orientation of the 200 reflection. the saxs data indicate that the lamellar thickness and long period have not been affected by shear but the lamellar orientation is dependent on shear. the experimental data of spp crystallization from sheared melt may indicate a mesophase structure that is crucial to the shear effects on the final polymer multiscale crystalline structures. |
