Abstract

The present invention relates to a preparation method of a vinyl aromatic hydrocarbon-conjugated diene block copolymer using coupling polymerization with improved ion stability. According to the present invention, the preparation method of a vinyl aromatic hydrocarbon-conjugated diene block copolymer comprises the following steps of: (a) polymerizing a vinyl aromatic hydrocarbon monomer with an organolithium compound polymerization initiator in a hydrocarbon solvent to prepare a first mixture solution containing a vinyl aromatic hydrocarbon block; and (b) adding a conjugated diene monomer to the first mixture solution of the step (a) to form a conjugated diene block to the terminal of the vinyl aromatic hydrocarbon block, thereby preparing a second mixture solution containing a vinyl aromatic hydrocarbon block-conjugated diene block copolymer, wherein the preparation method comprises the step of (c) adding a Lewis acid to the first mixture solution before the initiation of polymerization of the vinyl aromatic hydrocarbon monomer of the step (a), during polymerization, or the termination of polymerization.
