More Information
Summary:A fluorine-containing polymer has a fluorine content of 50% by mass or more, a degree of unsaturation of 0.1 mEq/g or more, and a glass transition temperature of -20°C or higher, and the relationship between the maximum value E∗1 of the complex elastic modulus in the range of from -50°C to (glass transition temperature - 10°C) and the minimum value E∗2 of the complex elastic modulus in the range of from (glass transition temperature + 10°C) to 250°C satisfies the following inequality: E∗2/E∗1 ≤ 0.01.
