ABSTRACT:
Olefins are polymerized with superior activity, using a catalyst composition consisting essentially of (a) a transition metal catalyst component prepared by reacting a titanium or vanadium compound with the reaction product formed between an alcohol-adduct of a magnesium dihalide solid carrier and an organometallic compound or a metal of groups I to III of the periodic table, and (b) an organometallic compound catalyst component of a metal of Groups I to III of the periodic table.
