ABSTRACT:
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.
