Abstract
A process for producing polyethylene having a superior form and a narrower molecular weight distribution with a higher polymer yield is provided. In this process, a combination of a solid product (II) with an organoaluminum compound is used as a polymerization catalyst. This solid product is prepared by first reacting a trivalent metal halide with a divalent metal compound to form a solid product (I), which is then reacted with a halogen-containing transition metal compound and a halogen-free transition metal compound in the presence of a polysiloxane.
