Abstract
Provided are a block copolymer including a polymer block containing acrylonitrile or methacrylonitrile as a principal constituent, which is excellent in heat resistance, weatherability, oil resistance, flame retardancy, and low-temperature resistance and which can be economically produced; and a thermoplastic resin composition and an elastomer composition each containing the block copolymer. The block copolymer is produced by reversible addition-fragmentation chain transfer polymerization in the presence of a thiocarbonylthio group-containing compound.
