(57) [Summary] [Purpose] To impart vibration damping properties without impairing the inherent characteristics of thermoplastic resins and to improve impact resistance at low temperatures. [Structure] 97 to 50 parts by weight of a thermoplastic resin has a Tg of − It is in the range of 40 to 0 ° C and has a number average molecular weight of 30,000 to 3 to 50 parts by weight of 300,000 parts of A (BA) n or (AB) n type styrene-isoprene block copolymer or hydrogenated product thereof is blended. |
