Abstract
A high-damping elastomer composition comprises a styrene-isoprene-styrene triblock copolymer (component A) and a ethylene-methyl methacrylate random copolymer (component B). In the high-damping elastomer composition of the present invention, the styrene-isoprene-styrene triblock copolymer (component A) and the ethylene-methyl methacrylate random copolymer (component B) form a so-called “islands-in-the-sea” structure which may vary depending on the blending ratio therebetween. The components A and B are partially compatibilized with each other in a homogeneously mixed state in sea-island interfaces.
