The present invention provides a rubber modifier compound, a modified conjugated diene-based polymer comprising a functional group derived from the compound, a method for producing a modified conjugated diene-based polymer using the compound, a rubber composition comprising the modified conjugated diene-based polymer and the rubber composition It is about an old tire. Accordingly, the rubber modifier compound may be used as a modifier for rubber, in particular, a conjugated diene-based polymer, to be bonded to the conjugated diene-based polymer chain to easily introduce a filler affinity functional group. Therefore, the modified conjugated diene-based polymer prepared by using the rubber modifier compound may have excellent affinity with the filler, and as a result, the processed product (eg, tire) manufactured from the rubber composition including the polymer may have tensile strength, Wear resistance, rolling resistance and wet road resistance properties can be excellent. |
