An acrylic resin composition which comprises 100 parts by mass of a rubber-containing multi-stage polymer (I) and 0-10 parts by mass of a thermoplastic polymer (II) and which satisfies: (1) a molded object of the acrylic resin composition has a modulus in flexure, measured at a temperature of 23ºC and a testing speed of 2 mm/min in accordance with ISO 178, of 400 MPa or lower, (2) in an examination with a dynamic viscoelasticity measurement device in the tensile mode, the acrylic resin composition, in the temperature range of 80ºC and higher, shows a peak at 85ºC or higher, and (3) when the acrylic resin composition is extruded at a constant rate (1.57 cm 3 /min) under the conditions of a capillary diameter φ of 1 mm, an L/D of 16, and a temperature of 230ºC and the strand thereof is hauled at a constant rate (10 m/min), then the value of melt tension is 0.03 N or more. This acrylic resin composition has high weatherability, flexibility, and heat resistance. |
