摘　　要：通过加酯量、酯化温度、陈化温度和搅拌速率四因素三水平正交实验对以MgCl_2为载体的高效聚丙烯催化剂制备过程进行探讨,发现诸因素对催化剂性能的影响各自表现出较强的规律性。该催化剂用于丙烯聚合具有高活性、高定向性及长寿命,已达到国内外同类催化剂的水平。The dosages of internal donor, the temperatures of esterification and ageing state, and the agitating rate for the preparation of the MgCl_2 supported highly active polypropylene (PP) catalyst have been studied by means of orthogonaI tests. It has been found that these parameters had significant effects on the catalyst properties. The perfor- mance of the prepared PP catalyst is verified to be equivalent to that of the third generation catalyst system in terms of activity or stereospecificity.
