摘要： The present disclosure relates to a modified conjugated diene-based polymer having excellent affinity with a filler, a method for preparing the same, a rubber composition including the same and a tire manufactured using the rubber composition. The modified conjugated diene-based polymer according thereto has a tin-based compound-derived group bind on one end, and a silane-based compound-derived group bind on the other end, and therefore, may have excellent affinity with a carbon black-based filler as well as a silica-based filler. Accordingly, a rubber composition including the modified conjugated diene-based polymer may have excellent processability, and as a result, processed goods (for example, tires) manufactured using the rubber composition may have excellent tensile strength, wear resistance and viscoelastic property.
