METAL-LIGAND COMPLEX, CATALYST COMPOSITION COMPRISING SAME FOR ETHYLENE-BASED POLYMERIZATION, AND METHOD FOR PREPARING ETHYLENE-BASED POLYMER BY USING SAME

摘要

The present invention provides a metal-ligand complex, a catalyst composition comprising the same for ethylene-based polymerization, and a method for preparing an ethylene-based polymer by using same. The metal-ligand complex of the present invention in which a particular functional group is introduced at a particular location has high solubility and catalytic activity, and thus the catalyst composition comprising the same for ethylene-based polymerization can produce an ethylene-based polymer having excellent physical properties.
