Abstract
A conjugated diene-based polymer catalyzed with a lanthanide rare earth element, and having high linearity and improved compounding properties, and a method for preparing the same are provided. The conjugated diene-based polymer catalyzed with a lanthanide rare earth element has high linearity, and if applied to a rubber composition, may show excellent processability, tensile strength and viscoelasticity.
