<p>Disclosed is a fluorine-containing copolymer composition which contains repeating units derived from ethylene and TFE, can be used in the production of a thin film or similar by means of coating, and can be manufactured at a relatively low temperature. Further disclosed is a method for producing the fluorine-containing copolymer composition at a relatively low temperature. The disclosed fluorine-containing copolymer composition contains a fluorine-containing copolymer (hereafter ETFE) which contains repeating units derived from ethylene and repeating units derived from tetrafluoroethylene, and a medium mixture, which is formed from at least two kinds of medium selected from media which do not independently dissolve the ETFE at concentrations of 1 mass% or more at temperatures not greater than the melting point of the ETFE, and which has a solubility index of a specified value with respect to the ETFE, based on Hansen solubility parameters. The disclosed fluorine-containing copolymer composition has a temperature range which exhibits a uniform solution state at temperatures not exceeding the melting point of the ETFE.</p> |
