    • An improved method of making an olefin polymerization catalyst is disclosed. The method reacts essentially equimolar amounts of a Group 4 transition metal tetrahalide and a quinolinol or pyridinol in the presence of a C.sub.5 -C.sub.10 hydrocarbon at a temperature within the range of about 0.degree. C. to about 60.degree. C. The method gives high yields of quinolinoxy or pyridinoxy-substituted Group 4 transition metal trihalides in a single reaction step. Particularly when combined with an activator, the target compounds are excellent olefin polymerization catalysts.
    • 公开了制备烯烃聚合催化剂的改进方法。 该方法在约0℃至约60℃的温度下,在C5-C10烃存在下,基本上等摩尔量的第4族过渡金属四卤化物和喹啉醇或吡啶酚反应。该方法得到高产率 的喹啉氧基或吡啶氧基取代的第4族过渡金属三卤化物。 特别是当与活化剂组合时,目标化合物是优异的烯烃聚合催化剂。
