摘要： A modified conjugated diene-based polymer is provided, having remarkable processability and excellent tensile strength and viscoelasticity properties, and a rubber composition including the same is also provided. The modified conjugated diene-based polymer has a unimodal shape molecular weight distribution curve by gel permeation chromatography, narrow molecular weight distribution and a Mooney stress-relaxation ratio of 0.7 or more, and includes a functional group derived from a modifier represented by Formula 1, and thus has remarkable processability and excellent tensile properties and viscoelasticity properties.

摘要： A modified conjugated diene-based polymer, and more particularly, a modified conjugated diene-based polymer having a unimodal molecular weight distribution curve measured by gel permeation chromatography (GPC), molecular weight distribution (PDI; MWD) of less than 1.7, and a Si content of 100 ppm or more based on weight, and including a repeating unit derived from an aromatic vinyl monomer in an amount from 15 wt % to less than 30 wt %, and a rubber composition including the same.
