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.

Modified conjugated diene-based polymer and rubber composition comprising same

The present invention provides a modified butadiene-based polymer capable of enhancing dispersability of an inorganic filler when used in a rubber composition, and enhancing viscoelasticity, a tensile property and processibility of the rubber composition in a balanced way from an interaction with the inorganic filler, and a modifier useful for preparing the same.
