Abstract
An improved process for polymerizing or copolymerizing an alpha-olefin containing at least 3 carbon atoms or for copolymerizing said alpha-olefin with not more than 10% by moles of ethylene, in the presence of a catalyst composed of (a) a component of transition metal catalyst derived from a solid carrier, an electron donor and a titanium compound, and (b) an organometallic compound of a metal of groups i to iii of the periodic table; wherein the improvement comprises that said transition metal component (a) is a solid transition metal component obtained by reaction of (1) a magnesium-containing reaction product, derived from a member of the group consisting of (1) a magnesium halide, (II) a compound containing active hydrogen, (III) an ester of organic acid and (IV) a silicon or tin compound, containing at least one halogen atom or a hydrocarbon group, directly bonded to silicon or tin, with (2) a titanium compound.
