Abstract

PURPOSE: To prepare a highly stereoregular polyolefin in high yield without a catalyst residue-removing process, by using a catalyst system comprising a component consisting of a magnesium compound, an electron donor, a titanium compound, etc., an organometallic compound component and an electron donor component.
CONSTITUTION: Olefins (e.g. propylene) are polymerized in the presence of a catalyst system comprising (A) an addition product of (a) a magnesium compound (e.g. magnesium chloride), (b) an electron doner (e.g. ethyl benzoate) and (c) a titanium halide (e.g. titanium tetrachloride) or a vanadium compound, or a material containing the addition product, (b) an organometallic compound I (M1 is alkali metal; X, Y, Z and W are 1W20C hydrocarbon, H, alkoxy, amine, etc.) or II (M2 is alkaline earth metal), or their combination with a compound III (B is hydrocarbon; n is integer of 1W3), and (C) an electron donor.
