ABSTRACT:
A high activity supported catalytic component obtained by pulverizing together (a) an anhydrous magnesium halide and (b) a titanium compound in the concomitant presence of 0.1 to 20 wt. % of (c) a liquid aromatic hydrocarbon and/or a liquid aromatic hydrocarbon halide, within the supported catalytic component, at temperature between 0.degree. and 100.degree. C. at which the liquid aromatic hydrocarbon and/or the liquid aromatic hydrocarbon halide remains in a liquid state throughout the whole range of temperature during the pulverization; and a method in which .alpha.-olefin is homo- or co-polymerized in the presence of a catalytic system comprising the high activity supported catalytic component, an organo-aluminum compound and an electron donor.
