    摘要: A vibration-damping thermoplastic resin composition comprising (a) 50 to 90 wt % of an amorphous thermoplastic resin (component A) having a loss tangent (tan &dgr;) value of 0.01 to 0.04 and a deflection temperature under load of not lower than 120° C. and (b) 50 to 10 wt % of a methyl methacrylate resin (component B), wherein an article molded from the resin composition has the following physical properties (1) to (4), i.e., (1) a loss factor of 0.04 to 0.08, (2) a water absorption of not higher than 0.30 wt %, (3) a specific gravity of 1.05 to 1.3, and (4) a deflection temperature under load of 110 to 170° C.; and an article molded therefrom. According to the present invention, a thermoplastic resin composition and an article molded therefrom which are excellent in vibration dampability as well as dimensional accuracy, rigidity and heat resistance and are light in weight, is provided.
