The invention provides a conjugated diene-vinyl arene copolymer modified on a tail end, and a synthetic method thereof. The synthetic method comprises: first, reacting conjugated diene monomer with vinyl arene monomer to generate a conjugated diene-vinyl arene copolymer, then, modifying the conjugated diene-vinyl arene copolymer and adding tin-containing radical on the tail end and -CM-N< linkage radical, wherein M is sulphur atom or oxygen atom. The consistency and mixing homogeneity of the conjugated diene-vinyl arene copolymer modified on the tail end with carbon black are good, so the conjugated diene-vinyl arene copolymer modified on a tail end is suitable to be used to manufacture tires in excellent quality. In addition, a conjugated diene-vinyl arene copolymer modified on a tail end is provided.
