Abstract
A vibration damper of the invention is formed from a polymer composition including (a) 100 parts by weight of a block copolymer including a polymer segment mainly derived from a vinyl aromatic compound and a polymer segment mainly derived from a conjugated diene compound, or a hydrogenated product of the copolymer, (b) 30 to 200 parts by weight of an ethylene.α-olefin copolymer having a kinematic viscosity at 100° C. of 300 to 5000 mm/s and an ethylene structural unit content of 30 to 80 mol %, and (c) 0 to 100 parts by weight of a polyolefin resin having a MFR of 0.1 to 500 g/10 min. According to the present invention, vibration dampers are provided which exhibit excellent vibration damping properties and transparency and show excellent weather resistance with little discoloration, and polymer compositions are provided which are suited for the production of vibration dampers having excellent vibration damping properties and weather resistance.
