用调节剂改善聚丙烯高效催化剂性能的研究

Effects of modifier on high-activity catalyst for prophlene ploymerization

在原聚丙烯合成催化剂的基础上,通过在制备过程中加入调节剂,制备了一种新型催化剂。试验结果表明新型催化剂与原催化剂相比,表面形态也得到明显改善,具有更高的活性、优良的动力学性能。

Based on the preparation process of original catalyst for propylene polymerization, a new catalyst for the propy- lene polymerization was prepared by adding some modifier. The results show that the morphology of the new catalyst has been improved, and its productivity and kinetic behavior are better than the original one.
