| abstract |
The present invention relates to a modified conjugated diene-based polymer and a rubber composition comprising the modified conjugated diene-based polymer, the modified conjugated diene-based polymer having a single A peak-shaped molecular weight distribution curve and a narrow molecular weight distribution, and the modified conjugated diene-based polymer contains a functional group derived from a modifying monomer represented by Formula 1 and a functional group derived from a modifier, thereby achieving excellent processing properties, tensile properties and viscoelastic properties. |
