METAL-LIGAND COMPLEX, CATALYST COMPOSITION FOR PREPARING ETHYLENE-BASED POLYMER CONTAINING THE SAME, AND PREPARATION METHOD OF ETHYLENE-BASED POLYMER USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2022/144650

Kind Code:

A1

Abstract:

Provided are a metal-ligand complex having both a strong electron donor group and an electron withdrawing group by introducing a specific functional group, difluoromethylene group, into an oxygen-oxygen bridge, a catalyst composition for ethylene-based polymerization containing the same, and a preparation method of an ethylene-based polymer using the same. The metal-ligand complex according to the present invention and the catalyst composition containing the same may be very usefully used in the preparation of an ethylene-based polymer having excellent physical properties.
