METHOD FOR PREPARING OLEFIN OLIGOMER

摘要

The present invention relates to a method for preparing an olefin oligomer, comprising a step of contacting an olefin monomer with a complex catalyst, the complex catalyst including an organic ligand which contains a diphosphonoamine compound in which a transition metal compound; a co-catalyst; and at least two diphosphonoamines are bonded via a polyvalent functional group in the presence of a halogenated organic solvent.
