<p>Solid catalytic components for the polymerization of olefins, which are obtained by bringing a magnesium compound, a titanium compound and an electron-donating compound into contact with each other, and then bringing the obtained solid component into contact with an alcohol; and catalysts for the polymerization of olefins, which comprise the solid catalyst component, an aluminum compound of the general formula: R1pAlQ3-p and an organosilicon compound of the general formula: R2qSi(OR3)4-q. The use of the above catalysts provides polyolefins excellent in stereospecificity in high yields.</p> |
