| titleOfInvention | Thermoplastic resin composition reduced in rattling sound, and molded article |
| abstract | [Problem] To provide a thermoplastic resin composition which enables the achievement of a molded article that is reduced in rattling sound and is also reduced in squeaking sound, while having good gloss. [Solution] A thermoplastic resin composition which is composed of at least a rubber-reinforced resin (A) that has a rubbery part (a1) and a resin part (a2), and which is configured such that: the rubbery part (a1) comprises a rubbery part (a1-1) that is derived from a block copolymer or a hydrogenated product thereof, said block copolymer containing a block (I) which is provided with a structural unit derived from an aromatic vinyl compound and a block (II) which is provided with a structural unit derived from isoprene or isoprene and butadiene, while having a main dispersion peak of tanδ at 0°C or higher; and the minimum value of the loss coefficient (η) in the frequency region of 20-12,400Hz is 0.02 or more if determined at 23°C by a center excitation method in accordance with JIS K 7244-1 with use of a test piece that is formed by cutting a flat plate having a thickness of 2 mm, which has been molded from this thermoplastic resin composition using an injection molding machine, into a piece that has a length of 250 mm, a width of 10 mm and a thickness of 2 mm. |
