| titleOfInvention | Method for producing prepolymerization catalyst component and method for producing propylene polymer |
| abstract | An object of the present invention is to provide a method for producing a pre-polymerization catalyst component capable of sufficiently reducing the amount of fine powder contained in a produced propylene polymer and stably producing a target propylene polymer. [Solution] A contact treatment product adjusting step for adjusting a contact treatment product by contacting an electron donor compound with a solid catalyst component containing titanium, magnesium and halogen in the absence of a propylene monomer and an organoaluminum compound, and the contact treatment A pre-polymerization catalyst preparation step for contacting the product with the propylene-based monomer, and then contacting the contact-treated product with the organoaluminum compound in the presence of the propylene-based monomer to adjust the pre-polymerization catalyst; A prepolymerization catalyst component production method comprising a prepolymerization catalyst component preparation step of preparing a prepolymerization catalyst component by polymerizing a propylene-based monomer using a catalyst. [Selection figure] None |
