<P>PROBLEM TO BE SOLVED: To provide an elastomer composition improved in rupture strength and compression set, and an elastomer composition obtained by irradiating the elastomer composition with active energy ray. <P>SOLUTION: The elastomer composition contains (A) 100 pts.mass of a thermoplastic elastomer and (B) 5-180 pts.mass of an active energy ray-curable liquid oligomer, and the elastomer composition irradiated with active energy ray, the elastomer composition may further contain (C) 40-450 pts.mass of a non-aromatic softening agent, (D) 0.01-10 pts.mass of a photopolymerization initiator, and (E) 0.5-20 pts.mass of polypropylene or the like. An elastomer composition obtained by irradiating the elastomer composition with active energy ray is also provided. The elastomer composition is used for an acoustic member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
