摘要： A block copolymer 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 excellent mechanical properties can be advantageously prepared by (a) batchwise preparing the specified living polymer (i.e. prepolymer) of at least one aromatic vinyl hydrocarbon polymer block by using a portion of monomers, and, then, (b) continuously preparing the block copolymer for continuously polymerizing the remainder of the monomers by continuously supplying the prepolymer to the first polymerization vessel of a continuous polymerization zone and simultaneously supplying the remainder of the monomers in the form of a monomer composed mainly of the aromatic vinyl hydrocarbon and/or a monomer composed mainly of the conjugated diene continuously and separately to the subsequent polymerization vessel(s). 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).
