In the present article, a novel spherical starch-supported vanadium (V)-based Ziegler-Natta catalyst was synthesized. The active centers of the obtained catalyst well dispersed in the starch through the SEM-EDX analysis. The effects of reaction conditions on ethylene polymerization were studied. The synthesized catalyst exhibited high activity toward ethylene polymerization in the presence of ethylaluminium sesquichloride (EASC) cocatalyst. Interestingly, the fiber shape PE was obtained directly during the polymerization process.
在本文中，合成了一种新型的球形淀粉负载钒（V）基齐格勒-纳塔催化剂。通过扫描电子显微镜-能谱分析（SEM-EDX）可知，所得催化剂的活性中心在淀粉中分散良好。研究了反应条件对乙烯聚合的影响。在倍半氯化乙基铝（EASC）助催化剂存在下，合成的催化剂对乙烯聚合表现出高活性。有趣的是，在聚合过程中直接得到了纤维状聚乙烯。
