<p><P>PROBLEM TO BE SOLVED: To provide a novel high damping composition that contains an S-IB diblock copolymer and an S-IB-S triblock copolymer together as a base polymer, and can form a high damping member that has a high damping performance and a large fracture elongation enough for being used as a vibration control damper of a building etc. <P>SOLUTION: A calcium carbonate is combined into the S-IB diblock copolymer and the S-IB-S triblock copolymer as a filler. A tackifier may be combined as well. As the tackifier, a hydrogenated petroleum resin is preferable which has a softening point of lower than 125°C. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
