CROSS-LINKED COMPOSITION, METHOD FOR PRODUCING CROSS-LINKED COMPOSITION, AND MOLDING

摘要

A crosslinked composition is obtained by crosslinking a composition, containing: 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 0.1 to 30% by mass of a conjugated diene monomer unit and having one or more tan ´ peak temperatures between 75°C and 125°C and having one or more tan ´ 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).
