(57) [Summary] [Structure] The content molar ratio of tetrafluoroethylene / ethylene is 50 to 60/50 to 40, respectively, and the content of the fluorine-containing vinyl monomer copolymerizable with them is 2 to 2. A novel ETFE copolymer characterized by being 7 mol%. [Effect] In addition to the characteristics of the conventional ETFE copolymer, a polymer having improved flexibility, transparency, and moldability by lowering the melting point can be obtained. |
