Abstract
The present disclosure relates to a polymerization initiator and a modified conjugated diene polymer prepared using the same, and more particularly to a polymerization initiator which is a compound represented by the following formula 1, and a modified conjugated diene polymer prepared using the same:wherein R1 to R5 are each independently hydrogen or a C1-10 alkylgroup or its carbanion; n− represents the number of negative charges of the carbanion and is 1− to 5−; M is a metal; and n is equal to the number of carbanions in R1 to R5.
