Abstract of the Invention Polyethylene or copolymers of ethylene with another .alpha.-olefin can be produced by the use of a novel polymerization catalyst obtained by using, in combination, (A) a specified, hydrocarbon-insoluble solid component prepared by reacting (i) a specific, hydrocarbon- soluble organoaluminum-magnesium complex (AlnMgmR?(3-.alpha.)- Image wherein R1 and R2 are hydrocarbon radicals) with (ii) a titanium or vanadium compound containing halogen atom(s), and (B) an organoaluminum compound. This catalyst exhibits a surprisingly high activity per the unit amount of the solid component.
