Abstract
A modified conjugated diene-based polymer including a repeating unit from a conjugated diene-based monomer; a derived unit from an N-containing aromatic hydrocarbon compound; a derived unit from an S-containing aromatic hydrocarbon compound or an S-containing heterocycle compound, and Si. Each of Si content and N content is 50 ppm or more based on the total weight of the polymer. The modified conjugated diene-based polymer satisfies the following conditions: (i) molecular weight distribution (PDI; MWD): 1.0 or more and less than 3.0; and (ii) a S content is 25 ppm or more based on a total weight of the polymer.
