NOVEL METALLOCENE COMPOUND, CATALYST COMPOSITION COMPRISING THE SAME, AND METHOD OF PREPARING OLEFIN-BASED POLYMERS USING THE SAME (AS AMENDED)

摘要

This invention relates to a novel metallocene compound, a catalyst composition including the same and a method of preparing olefin-based polymers using the same. The use of the novel metallocene compound as a catalyst for preparing olefin-based polymers enables synthesis of an olefin-based polymer having a low molecular weight and a wide molecular weight distribution.
