Kind Code:
A1
Abstract:
Provided is, in a shape (for example, a pellet) that can be handled easily, a thermoplastic elastomer composition that contains liquid rubber and that can be used to manufacture a molded article in which bleeding is suppressed and which exhibits desired mechanical characteristics. This pellet is of a thermoplastic elastomer composition that contains: 100 parts by mass of a block copolymer (X) including a polymeric block (A) that has a structural unit derived from an aromatic vinyl compound and a polymeric block (B) that has a structural unit derived from a conjugated diene compound; and not less than 10 parts by mass but less than 150 parts by mass of a liquid rubber component (Y). An antiblocking agent exists in a state of being in contact with the surface of the pellet. The contained amount of the antiblocking agent, including the amount exiting on the surface of the pellet, is 0.1-1.5 parts by mass with respect to 100 parts by mass of the pellet.
