Abstract
The present invention relates to a novel ligand compound, a metallocene compound, and a method for preparing an olefin-based polymer using the same. The metallocene compound according to the present invention and a catalyst composition comprising the same have excellent polymerization activity, and yet, have excellent comonomer insertion capability, and thus, can be used to prepare olefin-based polymer having wide molecular weight distribution and the resulting excellent processability.
