A method of polymerizing alpha-olefins, which comprises polymerizing or copolymerizing at least one alpha-olefin in the presence of a catalyst formed from
(A) a titanium-containing component at least containing magnesium, titanium and halogen, said component being obtained by co-pulverizing a mixture at least comprising (a) a magnesium compound, (b) a titanium compound and (c) at least 150 parts by weight, per 100 parts by weight of the magnesium compound (a), of an organic halogen compound, and optinoally contacting the resulting solid component with (d) a halogen-containing organoaluminum compound, and
(B) an organoaluminum compound component.
