| titleOfInvention | Solid catalyst component for olefin-based polymerization, method for producing the same, and method for producing an olefin-based polymer |
| abstract | Provides: when olefins are polymerized, especially when propylene and ethylene are subjected to a copolymerization reaction such as random copolymerization or block copolymerization, the adhesion (adhesion) derived from polymer particles is extremely low, and fluidity can be generated A solid catalyst component for olefin-based polymerization of an excellent polymer with good particle size distribution. A solid catalyst component for olefin polymerization, which is characterized by comprising: titanium, magnesium, halogen atoms and internal electron donors, the pore volume distribution measured by mercury porosimetry is multimodal, and the pore radius is 0.002 μm to 1 μm. The range and the range of the pore radius exceeding 1 μm and 30 μm or less each have one or more peaks, and the pore volume V1 derived from the pores in the range of radius 0.002 μm to 1 μm / the pores originating in the range of radii exceeding 1 μm and 30 μm or less The ratio shown by the pore volume V2 is 0.30 to 0.65. |
