Abstract: A block copolymer comprising at least one polymer block [A] and at least one polymer block [B]. The polymer block [A] mainly comprises repeating units having an alicyclic structure, while the polymer block [B] comprises repeating units having an alicyclic structure and repeating units derived from a diene monomer and/or vinyl monomer. In each block, the carbon-carbon unsaturated bonds have been hydrogenated. The block copolymer is molded into an optical disk, lightguide plate, film, sheet, container, optical lens, etc.
