Abstract

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 (Al.sub.n Mg.sub.m R.sub.n(3.sub.-.sub..alpha.).sup.1 -R.sub.2m.sup.2 H.sub.n, wherein R.sup.1 and R.sup.2 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.
