Title:
LIGAND COMPOUND, ORGANOCHROMIUM COMPOUND, CATALYST SYSTEM FOR ETHYLENE OLIGOMERIZATION, METHOD FOR PREPARING SAME AND ETHYLENE OLIGOMERIZATION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/077472
Kind Code:
A1
Abstract:
The present invention relates to a ligand compound, an organochromium compound, a catalyst system for ethylene oligomerization, to a method for preparing same and to an ethylene oligomerization method using same. The catalyst system for ethylene oligomerization according to the present invention may maintain high catalyst activity and alpha-olefin selectivity in the form supported by a carrier. Thus, low-density polyethylene or the like can be prepared in a single reactor using just ethylene monomers with less amount of or even no comonomers such as alpha-olefin.
