Abstract
PURPOSE: To obtain polyethylene having a wide MW distribution, excellent physical properties and excellent moldability in high catalytic efficiencies, by polymerizing ethylene in two reaction zones by using a catalyst consisting of a chromium compound and an organomagnesium compound.
CONSTITUTION: A process for polymerizing ethylene alone or together with other α-olefins in the presence of a catalyst consisting of a solid component prepared by allowing an inorganic compound to support a chromium compound and baking the inorganic compound and an organomagnesium compound of the formula, in two different reaction zones A and B, wherein in said reaction zone A, a polymer, MW 1,000W100,000, in an amount corresponding to 25W75% of the total amount of polymer is prepared by using an organomagnesium compound of the formula, wherein α/β≥3, 0.7≤γ/(α+β)≤1.5 and in said reaction zone B, a polymer, MW 100,000W1,000,000, is prepared by using an organomagnesium compound of the formula, wherein α/β≤1 and 0<γ/(α+β)≤0.5.
