The present invention provides a conjugated diene polymer, formulations, and manufacturing methods for the same. The present invention provides a conjugated diene polymer obtained by polymerizing conjugated diene monomers and vinyl aromatic monomers using an initiator by way of an anionic polymerization, the conjugated diene polymer comprising a plurality of blocks having more than 6 consecutive vinyl aromatic units, wherein a vinyl aromatic monomer content of the plurality of blocks having more than 6 consecutive vinyl aromatic units is less than 5 wt% based on a total vinyl aromatic monomer content of the conjugated diene polymer. The present invention also provides formulations for preparing the conjugated diene polymer and the manufacturing methods for the same.
