FLUORINE-CONTAINING COPOLYMER COMPOSITION

摘要

To provide a fluorinated copolymer composition from which a molded product excellent in the heat resistance and the stress crack resistance can be produced with good productivity. A fluorinated copolymer composition comprising ETFE and copper oxide, wherein the ETFE has repeating units (A) based on ethylene, repeating units (B) based on tetrafluoroethylene and repeating units (C) based on another monomer, in a molar ratio of the repeating units (A) to the repeating units (B) of from 38/62 to 44/56, and contains the repeating units (C) in an amount of from 0.1 to 2.6 mol% in all the repeating units of the ETFE; the content of the copper oxide is from 0.2 to 10 ppm based on the ETFE; and the volume flow rate of the fluorinated copolymer composition at 297°C is from 15 to 150 g/10 min.
