| 中文摘要 | a notable amount of pp beta-crystal (30%, by x-ray diffraction pattern) has been found in the pp samples as polymerized at normal static isothermal crystallization conditions without using any extra nucleating agents. existence of catalyst residues in the sample is decisive, which slows down the crystallization rate facilitating the formation of beta-form spherulites. comparatively, high molecular weight pp favors the formation of beta-form spherulites, deducting from no beta-crystal detected in the degraded samples. finally, high isotacticity is also required for obtaining qualitative beta-form spherulites, demonstrated by increased beta-crystal content after removal of weak crystalline fraction of the sample. |
