Title:
SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, CATALYST FOR OLEFIN POLYMERIZATION, AND METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2017/188180
Kind Code:
A1
Abstract:
Provided is a solid catalyst component for olefin polymerization which contains an electron-donating compound other than a phthalic acid ester, wherein, compared to when a phthalic acid ester is used as an electron-donating compound, a similar olefin polymerization activity is obtained, and a polymer obtained has a high stereo-regularity and a wide molecular weight distribution. The solid catalyst component for olefin polymerization is characterized by containing magnesium atoms, titanium atoms, halogen atoms, an ester compound (A) represented by general formula (1), and a diester compound (B) represented by general formula (2), and a ratio represented by formula (ester compound (A) content (mass%) / diester compound (B) content (mass%)) is 0.01-75.
