Abstract
A modified conjugated diene-based polymer having high linearity and improved compounding properties is provided. The modified conjugated diene-based polymer includes phosphor, sulfur and chlorine in specific amount ranges, and the degree of branching is controlled, and accordingly, if applied to a rubber composition, tensile strength and viscoelasticity may be excellent, and processability may be markedly improved.
