SOLID TITANIUM CATALYST INGREDIENT, CATALYST FOR OLEFIN POLYMERIZATION, AND METHOD OF OLEFIN POLYMERIZATION

摘要

The present invention relates to a solid titanium catalyst component containing magnesium, titanium, halogen and a specific ester compound; a catalyst for olefin polymerization containing the solid titanium catalyst component, an organometallic compound catalyst component and an electron donor where necessary; and a polymerization method of an olefin using the catalyst for olefin polymerization. According to the present invention, an olefin polymer having a high Mw/Mn value which is an index of the molecular weight distribution is obtained, even by a single-stage polymerization. Especially an olefin polymer having a high Mz/Mw which is a high content of high molecular weight components is obtained.
