  • LIGAND COMPOUND, ORGANIC CHROMIUM COMPOUND, CATALYST SYSTEM FOR ETHYLENE OLIGOMERIZATION, PREPARATION METHOD THEREOF, AND ETHYLENE OLIGOMERIZATION METHOD USING THE SAME
    Publication number: 20150298110
    Abstract: 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.
