Tridentate nitrogen-based ligand for olefin polymerization catalyst

Title:

Tridentate nitrogen-based ligand for olefin polymerization catalyst

Document Type and Number:

Japanese Patent JP6360549

Kind Code:

B2

Abstract:

Catalyst systems and methods for making and using the same are provided. A method for forming a polymer catalyst includes reacting a bromoketone compound with an aryl amine compound to form an amide compound. The amide compound is reacted with an ethylene diamine compound, to form a terminal primary amine compound. The terminal primary amine compound is reacted with a bromoaryl compound to form a ligand.
