Title:
METHOD FOR PRODUCING SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING CATALYST FOR OLEFIN POLYMERIZATION, AND METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/091938
Kind Code:
A1
Abstract:
Provided is a method for producing a solid catalyst component for olefin polymerization, the method being characterized by having: a first production step for obtaining a contact product by bringing titanium tetrachloride, a magnesium compound, an internal electron-donating compound and an inert organic solvent into contact with each other; a washing step for obtaining a washed product by washing the contact product obtained in the first production step with an inert organic solvent; and a second production step for obtaining a solid catalyst component by bringing the washed product obtained in the washing step, silicon tetrachloride, an organic acid chloride or metal chloride and an inert organic solvent into contact with each other. According to the present invention, it is possible to provide a method for producing a solid catalyst component for olefin polymerization, the method enabling the yield of a catalyst capable of producing an olefin polymer having excellent stereoregularity and whose catalytic activity does not become excessively low when an olefin is polymerized using a catalyst obtained using the solid catalyst component, which contains titanium, a halogen, magnesium, an internal electron-donating compound and an alkoxy group.
