Abstract
The present invention provides a catalyst composition including a functionalizing agent of the following Formula 1 together with a rare earth metal compound, an alkylating agent, and a halogen compound, having good catalytic activity and polymerization reactivity and useful for the preparation of a conjugated diene-based polymer having high linearity and excellent processability, and a conjugated diene-based polymer prepared using the catalyst composition. (X1)a-M1-([Y-M2-(X2)n-1])m-a [Formula 1]In Formula 1, a, m, n, M1, M2, X1, X2 and Y are the same as defined in the disclosure.
