The present invention relates to a polymer compound used as a polymer modifier, a conjugated diene-based polymer including a functional group derived therefrom, and a method for preparing a modified and conjugated diene-based polymer using the polymer compound. A rubber modifier compound obtained therefrom is used as a modifier for rubber, particularly, as a modifier of a conjugated diene-based polymer and is bonded to a chain of the conjugated diene-based polymer to easily introduce a functional group having affinity with a filler.
