摘要

When polymerizing olefins, especially when conducting copolymerization reactions such as random copolymerization and block copolymerization of propylene and ethylene, the adhesion due to stickiness (adhesiveness) of the polymer particles is extremely low, and the fluidity And a solid catalyst component for olefin polymerization that can produce a polymer having a good particle size distribution. It contains titanium, magnesium, halogen atoms and internal electron donors, and the pore volume distribution measured by mercury porosimetry is multimodal, with a pore radius ranging from 0.002 μm to 1 μm and a pore radius exceeding 1 μm to 30 μm or less. Each having one or more peak tops, and a pore volume derived from pores having a radius in the range of 0.002 μm to 1 μm V1 / a pore volume derived from pores having a radius exceeding 1 μm and not exceeding 30 μm The solid catalyst component for olefin polymerization is characterized in that the ratio represented by V2 is 0.30 to 0.65.
