PROBLEM TO BE SOLVED: To provide a method for manufacturing a pellet of a block copolymer consisting of an efficient conjugated diene polymer block and aromatic vinyl polymer block without forming a flocculated mass caused by adhesion to each other. SOLUTION: A block copolymer having at least one block mainly polymerized with an aromatic vinyl monomer (a) and at least one block mainly polymerized with a conjugated diene monomer (b) is extruded into water dispersed with silica and talk through a die of an extruder, wherein the extruded block copolymer is cut in the water so as to manufacture a pellet. |
