Abstract

The present invention relates to a method for preparing a catalyst composition with improved catalytic activity by pre-treating a hydrogen-bonded lanthanide rare earth element compound and / or an oligomer form of a lanthanide rare earth element compound that causes a decrease in catalytic activity, and a method for preparing a conjugated diene polymer using the catalyst composition prepared therefrom.
