Abstract
PURPOSE: To prepare high-density polyethylene having high bulk density, in high efficiency, by the use of a polymerization catalyst composed of an organo-aluminum compound and a reaction product of a titanium halide with a specially treated magnesium halide.
CONSTITUTION: A polymerization catalyst composed of (A) a solid product obtained by reacting (a) a modified magnesium chloride prepared by dispersing 1 mole of magnesium chloride, ≥0.1 mole of a tin halide such as SnCl4 and ≥0.1 mole of a 1W5C alcohol in an inert solvent, and reacting at about 60W140°C for about 0.5 hours, with (b) about 1W20 moles of titanium halide (TiCl4, TiCl3, etc.) at about 60W120°C for about 0.5 hours, and (B) about 10W100 moles, based on 1 mole of the (A) component, of an organo-aluminum compound.
