Method for manufacturing solid catalyst component mixtures for olefin copolymerization, catalysts for olefin copolymerization, and olefin copolymers.

Abstract

This invention provides a mixture of solid catalyst components for olefin copolymerization that can be easily manufactured to produce olefin copolymers with superior rigidity and impact resistance under the same polymerization conditions. This invention is a mixture of solid catalyst components for olefin copolymerization, characterized by comprising: a first solid catalyst component for olefin copolymerization, which includes magnesium, titanium, halogens, and a succinate diester compound; and a second solid catalyst component for olefin copolymerization, which includes magnesium, titanium, halogens, and a phthalate diester compound; wherein the content of the first solid catalyst component for olefin copolymerization accounts for 1% by mass or more and less than 37% by mass of the total content of the first and second solid catalyst components for olefin copolymerization.
