Solid Titanium Catalyst Component, Olefin Polymerization Catalyst, Olefin Polymerization Method, And Propylene Polymer
Abstract: [Problem] To provide a solid titanium catalyst component, an olefin polymerization catalyst and an olefin polymerization method, each enabling the production of an olefin polymer at a high activity, said olefin polymer being superior in stereoregularity and molecular weight distribution to conventional olefin polymers. To provide a propylene polymer having different physical properties from conventional propylene polymers. [Solution] A solid titanium catalyst component (I) for producing an olefin polymer, said solid titanium catalyst component being characterized by comprising titanium, magnesium, a halogen and a cyclic polyvalent ester group-containing compound (a) represented by formula (1). A propylene polymer that is preferably obtained by the aforesaid olefin polymerization method and that has particular thermal properties mainly specified by differential scanning calorimetry (DSC).
