Abstract
A block copolymer comprising a polymer block [A] and a polymer block [B]. The polymer block [A] contains mainly a repeating unit having an alicyclic structure, and the polymer block [B] contains the repeating unit having an alicyclic structure and a repeating unit derived from a diene based monomer and/or a vinyl based monomer. In any block, the carbon-carbon unsaturated bonds are hydrogenated. The block copolymer is molded into optical disks, optical waveguides, films, sheets, containers, and optical lenses.
