Abstract:
The present invention relates to a ligand compound, a chromium compound, and a catalyst system including the same. The catalyst system including the ligand compound or chromium compound according to the present invention exhibits high catalytic activity in ethylene oligomerization reaction, and therefore, polyethylene can be prepared using a small amount of comonomers or using only ethylene without comonomers.
