Claim Text:
1. A crosslinked composition obtained by crosslinking a composition, comprising: 1 to 99 parts by mass of a vinyl aromatic copolymer rubber (I) comprising 5 to 70% by mass of a vinyl aromatic monomer unit and 2.85 to 30% by mass of a conjugated diene monomer unit and having one or more tan δ peak temperatures between 75° C. and 125° C. and having one or more tan δ peak temperatures between −70° C. and −25° C. as obtained by dynamic viscoelasticity measurement (1 Hz); 99 to 1 parts by mass of an ethylenic copolymer rubber (II); 10 to 100 parts by mass of an olefinic resin (III) based on 100 parts by mass of a total amount of the vinyl aromatic copolymer rubber (I) and the ethylenic copolymer rubber (II); and 0.01 to 50 parts by mass of a crosslinking agent (IV) based on 100 parts by mass of the total amount of the vinyl aromatic copolymer rubber (I) and the ethylenic copolymer rubber (II) wherein a softening point of the crosslinked composition is 135° C. or higher.
