Title:
OLEFIN POLYMERIZATION SOLID CATALYST COMPONENT, OLEFIN POLYMERIZATION CATALYST, MANUFACTURING METHOD FOR OLEFIN POLYMER, OLEFIN POLYMER, MANUFACTURING METHOD FOR PROPYLENE-BASED BLOCK COPOLYMER, AND PROPYLENE-BASED BLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2022/250034
Kind Code:
A1
Abstract:
Provided is an olefin polymerization solid catalyst component with which an olefin polymer having superior fluidity and high rigidity, even with a narrow molecular weight distribution, could be manufactured easily without having to apply complicated polymerization processing.　The present invention provides an olefin polymerization solid catalyst component that contains magnesium, titanium, and a halogen and that also contains aromatic carboxylic acid esters and 1,3-diether compounds, as internal electron-donating compounds, the olefin polymerization solid catalyst component being characterized in that the titanium content is 0.5-2.0 mass%, the aromatic carboxylic acid ester content in the total content of the internal electron-donating compounds is 40-60 mol%, and the 1,3-diether compound content in the total content of the internal electron-donating compounds is 40-60 mol%.
