Abstract:
1. A molding formed of a thermoplastic elastomer composition consisting essentially of: an aromatic vinyl-isoprene block copolymer (a) including two or more poly(aromatic vinyl) blocks each having a weight-average molecular weight of 14,000 to 100,000, in an amount of 55 to 95 wt %; an aromatic vinyl-isoprene diblock copolymer (b) including a poly(aromatic vinyl) block having a weight-average molecular weight of 14,000 to 100,000 in an amount of 5 to 30 wt %; and polyisoprene (c) having a weight-average molecular weight of 5,000 to 300,000, in an amount of 5 to 33 wt %; wherein the composition has an aromatic vinyl monomer unit content of 14 to 30 wt % based on the total amount of the components (a), (b), and (c).
