Method for Preparing Catalyst Composition and Method for Preparing Conjugated Diene-Based Polymer

Abstract: a method for continuously preparing a catalyst composition for preparing a catalyst composition having improved catalyst activity by pre-treating a hydrogen-bonded lanthanide rare earth element compound and/or an oligomer type of a lanthanide rare earth element compound of formula 1, which induce the deterioration of the catalyst activity, and a method for preparing a conjugated diene-based polymer using the catalyst composition prepared thereby are described,
