Abstract

PURPOSE: To obtain polyethylene having a wide MW distribution, excellent physical properties and excellent moldability in high catalytic efficiencies, by polymerizing ethylene in the pesence of a catalyst consisting of a chromium compound in two reaction zones.
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 organoaluminum compound of the formula, in tow 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 a compound of the formula, wherein 1≤n≤2, and in said reaction zone b, a polymer, MW 100,000W1,000,000, in an amount corresponding to 75W25% of the total amount of polymer is prepared by using a compound of the formula, wherein 2<n<3.
