Abstract:
The present invention relates to a process for preparing an olefin oligomer including a step of contacting an olefin monomer with a composite catalyst in the presence of a halogenated organic solvent, wherein the composite catalyst includes: a transition metal compound; a cocatalyst; and an organic ligand including a diphosphonoamine compound in which two or more diphosphonoamines are combined via a polyvalent functional group.
