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 molcular weight and a wide molcular weight distribution.

摘要： The present invention relates to a ligand compound, an organic chromium compound, a catalyst system for ethylene oligomerization, a preparation method thereof, and an ethylene oligomerization method using the same. The catalyst system for ethylene oligomerization according to the present invention is used to prepare a low-density polyethylene in one reactor by using a small amount of comonomers such as alpha-olefin or by using only ethylene without comonomers, because it maintains high catalytic activity and high alpha-olefin selectivity even though supported on a support.
