摘要：
A new method for the activation of crystalline magnesium chloride by polyethylene glycol was described. Polyethylene glycol could solubilize crystalline magnesium chloride. The resulting solution was used for the preparation of Ziegler-Natta propylene polymerization catalysts. These catalysts are highly active and stereospecific. The relationship between the catalytic activity and the Al/Ti ratio was studied in detail.
