Catalysts for olefin polymerization and methods for manufacturing olefin polymers

Abstract

This invention relates to a catalyst for olefin polymerization, characterized by comprising: (I) a solid catalyst component for olefin polymerization, comprising at least magnesium, titanium, halogen, and, as an internal electron-supplying compound, one or more compounds selected from succinate diester compounds and one or more compounds selected from phthalate diester compounds; (II) an organoaluminum compound; and (III) as an external electron-supplying compound, at least one or more compounds selected from alkoxysilane compounds and one or more compounds selected from (alkylamino)alkylsilane compounds. According to this invention, a catalyst for olefin polymerization capable of producing olefin polymers with high rigidity and high impact resistance, and a method for manufacturing olefin polymers using the catalyst, are provided.
