FLUOROPOLYMER AND FILM COMPRISING THE SAME

摘要

[PROBLEMS] To provide a fluorocopolymer excellent in transparency and in mechanical strength at ordinary temperature and high temperatures. [MEANS FOR SOLVING PROBLEMS] The fluorocopolymer comprises units derived from ethylene, units derived from tetrafluoroethylene, units derived from hexafluoropropylene, and units derived from a perfluoro(alkyl vinyl ether), wherein the molar ratio of the units derived from ethylene to the units derived from tetrafluoroethylene is from 10/90 to 60/40, the amount of the units derived from hexafluoropropylene is 0.1 to 1.0 mol% based on all units, and the amount of the units derived from a perfluoro(alkyl vinyl ether) is 0.1 to 1.0 mol% based on all units.
