Hydrogenated aromatic vinyl copolymer and molded article produced from the same

A hydrogenated aromatic vinyl copolymer obtained by hydrogenating a block copolymer comprising monomer units including an aromatic vinyl monomer and a conjugated diene monomer, wherein the block copolymer includes (A) 75 to 92% by mass of a constituent unit derived from the aromatic vinyl monomer and (B) 8 to 25% by mass of a constituent unit derived from the conjugated diene monomer (with the proviso that (A)+(B)=100% by mass) and is a branched block copolymer which has a weight average molecular weight of 100,000 to 300,000 and of which the block structure is shown by the following general formula (1) or (2),

• (A−B)nM (1)
• (A−B−A)nM (2)
• wherein A is the constituent unit derived from the aromatic vinyl monomer, B is the constituent unit derived from the conjugated diene monomer, M is at least one metallic element selected from the group consisting of Si, Sn, and Ge, and n is 2<n<4, and 97% or more of the aromatic rings derived from the aromatic vinyl monomer and the double bonds derived from the conjugated diene monomer are hydrogenated.
