摘要： A modified conjugated diene-based polymer represented by Formula 1, wherein a terminal of a polymer chain is modified, and a method for preparing same are provided. By including a modifier derived unit having a specific structure, a beta value affecting cold flow may be reduced through controlling the degree of branch, and accordingly, the cold flow of a polymer may be efficiently controlled and a mooney viscosity increasing ratio may be improved.

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.
