| description | The present invention provides a method for preparing a modified conjugated diene-based polymer characterized in adding a polyoxyethylene phosphate ester-based compound having a specific structure together with sulfur chloride modifier during modification, by which modification reproducibility may be markedly improved, stable process may be performed, the changing degree of the physical properties, specifically a mooney viscosity increasing ratio and the degree of branching of a modified conjugated diene-based polymer according to modification conditions may be anticipated, and the changing degree of a mooney viscosity increasing ratio and the degree of branching may be easily controlled by controlling modification conditions. |
