Abstract
The present invention relates to a modified conjugated diene-based polymer having a high modification ratio with improved compounding properties by being excellent affinity with a filler and a method for preparing the same. The modified conjugated diene-based polymer thus prepared includes a functional group derived from a compound represented by Formula 1 at one terminal, and has excellent affinity with a filler. If the modified conjugated diene-based polymer is applied to a rubber composition, excellent processability, tensile strength and viscoelasticity may be achieved.
