Abstract

The present invention relates to a catalyst composition comprising a novel transition metal compound and a preparation method for polyolefin using the same. The catalyst composition of the present invention has high catalytic activity for polymerization of olefin-based monomers and enables it to control the fine-structure characteristics of the polyolefin, such as molecular weight distribution, in a wide range, thereby easily providing a polyolefin with desired properties.
