Title:
MAIN CATALYST FOR PREPARING POLY(4-METHYL-1-PENTENE) AND USE OF MAIN CATALYST
Document Type and Number:
WIPO Patent Application WO/2024/051442
Kind Code:
A1
Abstract:
The present application provides a main catalyst for preparing poly(4-methyl-1-pentene) and a use of the main catalyst. The main catalyst for preparing poly(4-methyl-1-pentene) of the present application has a structure represented by formula I. In the formula I, R1 is selected from hydrogen or phenyl, and when R1 is selected from phenyl, R1 is fused with a benzene ring in the formula I to form an anthracene ring; and R2 is selected from methyl or isopropyl. When the main catalyst of the present application is used in a catalytic system to catalyze homopolymerization of 4-methyl-1-pentene, the catalyst exhibits high catalytic activity, and the prepared poly(4-methyl-1-pentene) has high molecular weight, narrow molecular weight distribution and high isotacticity, and thus has broad market application prospects.
