Hydrogenated block copolymer, vibration damper, sound insulator, interlayer for laminated glass, dam rubber, shoe sole material, flooring material, laminate, and laminated glass

A laminate comprising:

• an X layer comprising a hydrogenated block copolymer;
• and
• a plurality of Y layers laminated on at least one surface of the X layer;
• wherein
• the hydrogenated block copolymer is a hydrogenation product of a block copolymer comprising a polymer block (A) consisting of a structural unit derived from an aromatic vinyl compound and a polymer block (B) containing 30 mol % or more of a structural unit derived from at least one selected from the group consisting of a conjugated diene compound and isobutylene,
• wherein the content of the polymer block (A) in the block copolymer is from 1 to 12% by mass;
• and
• when the polymer block (B) is regarded as having a structure with a hydrogenation rate of 100 mol %, an average value of a methylene chain length of a main chain of the structural unit derived from at least one selected from the group consisting of a conjugated diene compound and isobutylene is from 1.0 to 6.0;
• wherein
• a weight average molecular weight (Mw) of the polymer block A is from 3,000 to 60,000,
• a weight average molecular weight of the polymer block B is from 130,000 to 450,000,
• a weight average molecular weight (Mw) of the hydrogenated block copolymer is from 133,900 to 800,000, and
• a bonding mode of the polymer block (A) and the polymer block (B) is selected from the group consisting of A-B, A-B-A, B-A-B, A-B-A-B, A-B-A-B-A, B-A-B-A-B and (A-B)n-X wherein A represents polymer block (A), B represents polymer block (B), n is an integer of 3 or more and X represents a coupling agent residue, and
• a morphology of a film having a thickness of 1 mm, which is obtained by molding the copolymer under the following molding condition, has a microphase-separated structure of a sphere:
• Molding condition:
• to apply a pressure at a temperature of under a pressure of 10 Mpa for 3 minutes,
• wherein at least one of the plural Y layers is a layer comprising a thermoplastic resin (i) different from the hydrogenated block copolymer, and
• the thermoplastic resin (i) is an ionomer.
