Abstract: Provided is a solid catalyst component for polymerization of olefins which is capable of producing a polymer that has very low adherence ascribable to the stickiness (tackiness) of polymer particles, is excellent in flowability, and also has a favorable particle size distribution, in order to polymerize olefins, particularly, to perform the copolymerization reaction, such as random copolymerization or block copolymerization, of propylene and ethylene. The solid catalyst component for polymerization of olefins comprises titanium, magnesium, a halogen atom and an internal electron donor, wherein the solid catalyst component has a multimodal pore volume distribution measured by a mercury intrusion method and has one or more peak tops in each of a pore radius range from 0.002 µm to 1 µm and a pore radius range from larger than 1 µm to 30 µm or smaller, and a ratio represented by pore volume V1 derived from pores in the radius range from 0.002 µm to 1 µm/pore volume V2 derived from pores in the radius range from larger than 1 µm to 30 µm or smaller is 0.30 to 0.65.

Abstract: A solid catalyst component for olefin polymerization makes it possible to polymerize an olefin with high polymerization activity when used for an olefin polymerization catalyst, and produce an olefin polymer having a low fine powder content, a low coarse powder content, and a low volatile organic compound (VOC) content in high yield. The solid catalyst component for olefin polymerization is produced by suspending (a) a dialkoxymagnesium, and (b) at least one alcohol selected from ethanol, n-propanol, n-butanol, isopropanol, isobutanol, and t-butanol, in an inert organic solvent so that the total amount of the alcohol is 0.5 to 1.5 parts by mass based on 100 parts by mass of the dialkoxymagnesium, to prepare a suspension, and bringing (c) an internal electron donor and (d) a titanium halide compound into contact with the suspension.
