| titleOfInvention | Solid catalyst component for olefin polymerization, method for producing the same, method for producing catalyst for olefin polymerization, and method for producing olefin polymer |
| abstract | The present invention relates to a solid catalyst component for olefin polymerization, a method for producing the same, a method for producing a catalyst for olefin polymerization, and a method for producing an olefin polymer. Provided is a solid catalyst component for olefin-based polymerization that produces a homopolypropylene polymer with high tacticity when used in an ethylene-propylene copolymerization reaction and can exhibit good ethylene-responsiveness. A solid catalyst component for olefin polymerization, characterized in that it contains: titanium, magnesium, halogen, and an internal electron-donating compound, wherein the internal electron-donating compound comprises: an electron-donating compound (i) having a phthalate structure; And, an electron-donating compound (ii) having two or more groups selected from ether groups, ester groups, and carbonate groups and not having a phthalate structure, the aforementioned having a group selected from ether groups, ester groups The content ratio of the electron-donating compound (ii) which does not have a phthalate structure with two or more groups in the carbonate group is 0.5 to 1.5 mass %. |
