Abstract

The present invention relates to a modified conjugated diene-based polymer having excellent affinity with a filler and a method for preparing the same, and provides a modified conjugated diene-based polymer including: a first chain comprising a repeating unit derived from a conjugated diene-based monomer; and one or more graft chains comprising a derived unit from an oligomer and graft-bonded to the first chain, wherein the derived unit from an oligomer comprises a residual group derived from a radical reactive functional group, and a molecular weight distribution increase ratio defined by Mathematical Equation 1 is 20% or less, and a method for preparing the same.
