The present invention relates to a rubber modifier, a conjugated diene polymer comprising a functional group derived from the modifier, and a method for preparing a modified conjugated diene polymer using the modifier. The resulting modifier can be used as a modifier of the conjugated diene polymer to be bonded to a chain of the conjugated diene polymer, thereby easily introducing a filler-affinity functional group. Accordingly, the modified conjugated diene polymer prepared using the rubber modifier compound can have excellent affinity with a filler, and as a result, a processed product (e.g., a tire) manufactured from a rubber composition containing the polymer can have excellent tensile strength, abrasion resistance, and wet road surface resistance characteristics. |
