Abstract

To provide a fluorinated copolymer composition having improved impact resistance and excellent moldability without impairing the excellent heat resistance and mechanical properties inherent to a thermoplastic heat-resistant resin. This fluorinated copolymer composition comprises a thermoplastic resin A being a melt-moldable heat-resistant thermoplastic resin and a fluorinated elastomer B being a fluorinated elastic copolymer, wherein the fluorinated elastomer B is dispersed in the thermoplastic resin A, the number average particle diameter of the fluorinated elastomer B is from 1 to 300 μm, the volume ratio of the thermoplastic resin A to the fluorinated elastomer B is from 97:3 to 55:45, and the fluorinated copolymer composition has a flexural modulus of from 1,000 to 3,700 MPa.
