摘要

Provided is a solid catalyst component for olefin polymerization, which has extremely low adhesion caused by stickiness (tackiness) of polymer particles during polymerization of olefins, especially during a copolymerization reaction such as random copolymerization or block copolymerization of propylene and ethylene, and which is capable of producing a polymer that has excellent fluidity and good particle size distribution. This solid catalyst component for olefin polymerization is characterized by: containing titanium, magnesium, a halogen atom and an internal electron donor; having a multimodal pore volume distribution as determined by mercury intrusion porosimetry; having one or more peak tops within the pore radius range of from 0.002 μm to 1 μm and within the pore radius range of from 1 μm (exclusive) to 30 μm (inclusive), respectively; and having a ratio expressed by (pore volume V1 derived from pores within the radius range of from 0.002 μm to 1 μm)/(pore volume V2 derived from pores within the radius range of from 1 μm (exclusive) to 30 μm (inclusive)) of from 0.30 to 0.65.
