Abstract
An improvement in the method for producing ethylene polymers by using a catalyst consisting of a combination of a following solid product with an organoaluminum compound is provided. Said solid product (III) is prepared by reacting a trivalent metal halide with a divalent metal compound; reacting the resulting reaction product with a transition metal compound in the form of liquid; reacting the resulting solid product (I) with an aluminum or boron alcoholate; and reacting the resulting solid product (II) again with a transition metal compound in the form of liquid to obtain said solid product (III). Ethylene polymers obtained according to this method have broader molecular weight distributions.
