Transition metal compound having heteroatom, catalystic composition including the same, and method for preparing polymers using the same

摘要

The present invention discloses a transition metal compound having a novel structure and including a heteroatom, a catalyst composition including the same, and a method for preparing polymers using the same. The transition metal compound according to an embodiment of the present invention has good copolymerization properties, and a polymer having a low density may be prepared using thereof. Thus, a copolymer having various uses may be prepared.
