摘要： A magnesium-supported catalytic component for α-olefin polymerization having an improved strength and a high stereoregularity while keeping a high catalytic activity, which is produced either by bringing (A) a solid component containing magnesium, titanium, halogen and an electron donating compound as the essential ingredients, into contact with (D) an olefin in the presence of (B) trialkylaluminum and (C) a dimethoxysilane compound of the general formula: R1R2Si(OCH¿3?)2, wherein R?1 and R2¿ may be the same or different from each other and each represents a C¿1? to C10 aliphatic hydrocarbon group, said compound having a volume of 230 to 500 Å?3¿ and an electron density of the oxygen atom of the methoxy group of 0.685 to 0.800 atomic unit, both calculated based on the theory of quantum chemistry, or by bringing (A) a solid component containing metal oxide, magnesium, titanium, halogen and an electron donating compound as the essential ingredients, into contact with (D) an olefin in the presence of (B) trialkylaluminum and (C) a dimethoxysilane compound of the general formula: R1R2Si(OCH¿3?)2, wherein R?1 and R2¿ may be the same or different from each other and each represents a C¿1? to C10 aliphatic hydrocarbon group, said compound having either a volume of 170 to 500 Å?3¿ and an electron density of the oxygen atom of the methoxy group of 0.690 to 0.800 atomic unit, both calculated based on the theory of quantum chemistry, or the volume of 200 to 500 Å3 and the electron density of 0.685 to 0.800 atomic unit.
