POLYMERIZATION INITIATOR HAVING ANIONIC END COMPRISING AMINE, METHOD FOR PREPARING MODIFIED CONJUGATED DIENE POLYMER USING THE SAME, AND RUBBER COMPOSITION COMPRISING MODIFIED CONJUGATED DIENE POLYMER PREPARED USING THE SAME

摘要

The present invention relates to an anionic polymerization initiator which is an organic alkali metal compound having an anionic end including an amine group, a preparation method of a modified conjugated diene-based copolymer using the same, and a rubber composition comprising the modified conjugated diene-based copolymer prepared using the same. Provided is a modified conjugated diene-based polymer is represented by any one of chemical formulas 1 to 3. The anionic polymerization initiator is a compound represented by chemical formula 4.
