The present invention relates to a method for terminating anionic polymerization by Lewis acid, and more particularly, by using Lewis acid as a polymerization terminator at the polymer active terminal when preparing a conjugated diene polymer prepared by anionic polymerization, polymerization is effectively prevented without coupling. It is terminated, there is no problem of discoloration, there is no base material that affects the antioxidant, and thus relates to an anionic polymerization terminating method capable of controlling acidity without the need for an additional neutralization process. |
