Patent ID: 11236189

Abstract:
A solid catalyst component for polymerization of olefins is disclosed which can produce a polymer having low stickiness (tackiness) of polymer particles, excellent flowability, and favorable particle size distribution. The solid catalyst component for polymerization of olefins includes 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.
