The title catalyst, useful for manuf. of polyethylene [9002-88-4] with increased melt index, was prepd. by heating TiCl4, Mg, C1-4 alkanol, and C2-10 alkyl chloride in a liq. hydrocarbon at 75-150°, then aging, and drying. The mol ratios of Ti/Mg and alc./TiCl4 were 3.25 × 10-3 to 3 × 10-2 and 0.5-3.5, resp.
