Production method of building a bridge composition and building a bridge composition,

摘要

PROBLEM TO BE SOLVED: To provide a crosslinked composition and a molded article excellent in flexibility, heat resistance (permanent compression strain at high temperatures), mechanical strength, and molding processability.;SOLUTION: The crosslinked composition is obtained by crosslinking a composition comprising (I) 1-99 pts.mass of a vinyl aromatic copolymer rubber containing 5-70 mass% of a vinyl aromatic monomer unit and 0.1-30 mass% of a conjugated diene monomer unit, and (II) 99-1 pts.mass of an ethylenic copolymer rubber, as well as, based on 100 pts.mass of the total amount of the vinyl aromatic copolymer rubber (I) and the ethylenic copolymer rubber (II), (III) 10-100 pts.mass of an olefinic resin, and (IV) 0.01-50 pts.mass of a crosslinker.;COPYRIGHT: (C)2011,JPO&INPIT
