| abstract |
The present invention provides a thermoplastic elastomer composition for a crosslinked foam that is lightweight and flexible and excellent in splitting strength, compression set, tear strength, impact resilience, and the like, and a method for producing the same. (A) an ethylene copolymer; (B) a first copolymer; (C) a second copolymer, wherein the components (B) and (C) are vinyl aromatic monomers. A copolymer comprising a monomer and a conjugated diene monomer, wherein the first copolymer has a conjugated diene hydrogenation rate of at least 80% and the second copolymer has a conjugate of 10% or less. Having a diene hydrogenation rate; (D) organic peroxide; and (E) blowing agent, wherein the mass ratio of the combination of component (A): component (B) and component (C) (A / (B + C)) ) Is 95/5 to 5/95 and the mass ratio (B / C) of component (B): component (C) is 9/1 to 1/9. Foam and its manufacturing method. [Selection figure] None |
