Summary: | A method for producing a stereoregular polyolefin in the presence of a catalyst comprising a transition metal compound and an organometallic compound, wherein a catalyst system is employed which comprises (i), (ii) and (iii): (A) a solid catalyst component obtained by reacting to a uniform solution containing (i) at least one member selected from the group consisting of metallic magnesium and an organic hydroxide compound and an oxygen-containing organic magnesium compound, (ii) a compound of Group IIIB of the Periodic Table, and (iii) an oxygen-containing organic silicon compound, (iv) at least one aluminum halide, to obtain a solid product, and reacting to the solid product, (v) an electron donative compound, and (vi) a titanium halide compound; (B) at least one member selected from the group consisting of organometallic compounds of metals of Groups IA, IIA, IIB, IIIB and IVB of the Periodic Table; and (C) an electron donative compound. |
