Title:
CATALYST FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING OLEFIN POLYMER, AND PROPYLENE HOMOPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/171435
Kind Code:
A1
Abstract:
Provided is a catalyst for olefin polymerization which contains a solid catalyst component for olefin polymerization including an internal electron-donating compound that is not a phthalic acid ester and with which nevertheless a propylene homopolymer excellent in terms of melt flowability and moldability and having an even higher bending modulus can be easily produced. The catalyst for olefin polymerization is characterized by comprising: a solid catalyst component for olefin polymerization which includes magnesium, titanium, a halogen, and a succinic acid diester compound and in which the ratio of the total content (S) of internal electron-donating compounds comprising the succinic acid diester compound as a main component to the content (T) of the titanium, S/T, is 0.60-1.30 by mole; an organoaluminium compound; and one or more external electron-donating compounds selected from among specific aminosilane compounds.
