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.
Claims9
A modified conjugated diene-based polymer, comprising:
- 240 to 470 ppm of phosphor (P) based on a weight of the modified conjugated diene-based polymer;
- 490 to 900 ppm of sulfur (S) based on a weight of the modified conjugated diene-based polymer;
- and
- 450 to 1100 ppm of chlorine (Cl) based on a weight of the modified conjugated diene-based polymer.
