Abstract
The present invention relates to a method for preparing an oligomerization catalyst system and the method comprises preparing a catalyst composition by mixing a PNP-based ligand compound and a transition metal compound, and mixing and activating a co-catalyst and the catalyst composition at a temperature from −40 to 80° C. The oligomerization catalyst system prepared by the method may maintain the activity thereof during an oligomerization reaction at a high temperature, and the reaction temperature of oligomerization may be easily controlled. Various merits in processing may be obtained.
