Abstract
Polyethylene or ethylene copolymer containing up to about twenty percent of a C.sub.3 to C.sub.8 olefin can be made by using a solid catalyst component prepared from (1) a lower alkyl magnesium alkoxide or magnesium hydroxide, (2) a titanium-aluminum compound, and (3) a lower alkyl alkylaluminum dichloride. Said solid component can be used in conjunction with a trialkylaluminum promoter in a slurry or vapor phase polymerization process at moderate polymerization temperatures and pressures.
