| abstract |
The present invention relates to a modified conjugated diene-based polymer having excellent processability and excellent tensile strength and viscoelastic properties, and a rubber composition including the same. Accordingly, the modified conjugated diene-based polymer has a narrow molecular weight distribution, a Mooney relaxation ratio of 0.7 or higher, and a molecular weight distribution curve by gel permeation chromatography with a unimodal form, and includes a modifier-derived functional group represented by the formula (1). It is excellent in tensile properties and viscoelastic properties. |
