Abstract

PURPOSE: To obtain an α-olefin polymer having a high bulk specific gravity with a high catalytic efficiency, by using a catalyst consisting of a combination of a solid product (A) of the reaction between a specific solid product (a) and a transition metal compound (b) in the presence of an electron donor with an organoalumimum compound (B).
CONSTITUTION: A solid product (a) obtained by reacting a trivalent metal halide, e.g. (anhydrous) AlCl3, with a bivalent metal hydroxide or oxide, e.g. Mg(OH)2 or MgO, is reacted with a transition metal compound (b), e.g. TiCl4, TiBr4, VCl4, or VOCl3, in the presence of an electron donor, e.g. an ether, ester, or an acid amide, to form a solid product (A). An α-olefin is polymerized in the presence of a catalyst consisting of a combination of the product (A) with an organoaluminium compound (B), e.g. triethylaluminum or diethyl-aluminum chloride.
