Furthermore, a block copolymer mixture containing two or more polymer blocks composed mainly of an aromatic vinyl hydrocarbon and one or more polymer blocks composed mainly of a conjugated diene having a high mutual interaction between the block copolymers therein can be advantageously prepared by (a) batchwise preparing the prepolymer and, then, (b) continuously preparing the block copolymers having the aromatic vinyl hydrocarbon contents thereof substantially continuously changed with an increase in the molecular weight of the block copolymers by broadening the molecular-weight distribution of at least one polymer block formed in the continuous polymerization zone (b).
