ABSTRACT:
A novel process for polymerizng ethylene or a mixture of ethylene and another olefin is provided. In this process a novel catalyst having a very high activity per solid component of catalyst is used. Said catalyst is prepared by reacting a specific hydrocarbon-soluble organoaluminum-magnesium complex containing alkoxy, aryloxy, siloxy or siloxane groups, with one or more kinds of a titanium or vanadium compound having at least one halogen atom, and subsequently reacting the thus obtained hydrocarbon-insoluble reaction product (A) with a specified organoaluminum compound (B).
