A thermoplastic resin composition which comprises (A) a thermoplastic polymer containing a unit containing glutaric anhydride and represented by the following general formula (1): (wherein R1 and R2 are the same or different and each represents hydrogen or C1-5 alkyl) and (B) a rubbery polymer and which satisfies the following (I) and/or (II): (I) the thermoplastic resin composition has a total light transmittance of 90% or higher per 2-mm thickness; and (II) the thermoplastic polymer (A) has a weight-average molecular weight of 30,000 to 150,000 and a glass transition temperature of 130°C or higher. The thermoplastic resin composition has high heat resistance, mechanical properties, colorlessness, transparency, optical isotropy, and moldability and further has solvent resistance. |
