Abstract
A modified conjugated diene-based polymer and a rubber composition including the same are disclosed herein. The modified conjugated diene-based polymer has excellent storage stability and excellent processability, tensile strength and viscoelasticity properties. In some embodiments, a modified conjugated diene-based polymer includes a repeating unit derived from a conjugated diene-based monomer, and a functional group derived from an aminoalkoxysilane-based modifier, wherein the rate of change of molecular weight distribution calculated by Mathematical Formula 1 is 10% or less.
