Title:
METAL-LIGAND COMPLEX, CATALYST COMPOSITION FOR PRODUCING ETHYLENE-BASED POLYMER CONTAINING THE SAME, AND METHOD OF PRODUCING ETHYLENE-BASED POLYMER USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2023/126844
Kind Code:
A1
Abstract:
The present invention relates to a metal-ligand complex having significantly improved high-temperature activity due to an increase in resistance of a catalyst to impurities such as oxygen and moisture and stability through introduction of a specific functional group, a catalyst composition for preparing an ethylene-based polymer containing the same, and a method of producing an ethylene-based polymer using the same.
