<p>A solid catalyst component for olefin polymerization prepared from a magnesium compound, a halogenated compound of tetravalent titanium, an aromatic dicarboxylic acid diester, an aromatic hydrocarbon, and either a hydroxylated organic acid aluminum compound represented by the general formula: (R1CO2)mAl(OH)3-m or aluminum hydroxide through contacting; and a catalyst for olefin polymerization comprising this solid catalyst component, an organoaluminum compound represented by the general formula: R2pAlQ3-p, and an organosilicon compound represented by the general formula: R3qSi(OR4)4-q. In slurry polymerization, the catalyst inhibits the generation of low-molecular or lowly stereoregular polymers soluble in the polymerization solvent and is capable of yielding a highly stereoregular polymer in high yield. When the catalyst is used in the copolymerization of olefins, a copolymer having excellent properties can be obtained in high yield.</p> |
