The present invention relates to a modified conjugated diene-based polymer having an adjusted degree of branching, excellent affinity with a filler, excellent processability and compounding properties, a method for producing the same, and a rubber composition containing the same. The modified conjugated diene-based polymer according to this can be produced by using the modifying agent represented by the chemical formula 1, and the degree of branching of the polymer chain can be adjusted, so that the processability characteristics and the abrasion resistance are improved. By including the modifier-derived functional group at at least one end of the polymer chain, the affinity with the filler is excellent and the compounding property of the rubber composition containing the functional group can be improved. |
