Title:
SOLID CATALYTIC COMPONENT FOR OLEFIN POLYMERIZATION AND PRODUCTION METHOD THEREFOR, CATALYST FOR OLEFIN POLYMERIZATION AND PRODUCTION METHOD THEREFOR, AND PRODUCTION METHOD FOR OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2021/220644
Kind Code:
A1
Abstract:
Provided is a solid catalytic component that is for olefin polymerization and that, when used in olefin polymerization, allows easy formulation of an olefin polymer in which reduction in polymerization activity per unit time is suitably suppressed, improves the efficiency of drying, and quickly and significantly reduces the content ratio of residual volatile organic compounds, without using a phthalic acid ester.　This solid catalytic component for olefin polymerization comprises magnesium, titanium, a halogen, and a 1,3-diether compound, and is characterized in that the proportion of the 1,3-diether compound contained in the solid catalytic component for olefin polymerization is 2.50-15.00 mass%, and the specific surface area of the solid catalytic component for olefin polymerization is at least 250 m2/g.
