| titleOfInvention | Method for producing olefin-based polymerization catalyst and method for producing olefin-based polymer |
| abstract | Provides excellent catalytic activity at the time of polymerization treatment even when electron donating compounds other than phthalates are used, and enables production of excellent stereoregularity and bulk density, reduced fine powder and coarse powder A method for producing an olefin-based polymerization catalyst of an olefin-based polymer having an excellent content particle size distribution. A method for producing an olefin-based polymerization catalyst, comprising a step of: subjecting a solid catalyst component for olefin-based polymerization, a vinylsilane compound, a compound having at least one selected from the group consisting of an alkoxy group and an amino group to an inert gas atmosphere. An organosilicon compound having one group and no vinyl group, and an organoaluminum compound are contacted in an inert organic solvent in the absence of a specific vinyl compound, the solid catalyst component for olefin-based polymerization comprising a magnesium compound and titanium The halide contains an electron-donating compound having a diol skeleton and no phthalate structure, and after adding the aforementioned vinylsilane compound to the reaction system, cleaning treatment is not performed. |
