摘要：
A fluorine-containing terpolymer with distinguished transparency and strength at ordinary temperature and at elevated temperatures when heated, which comprises 20–98% by weight of tetrafluoroethylene, 1–40% by weight of perfluoro(ethyl vinyl ether) and 1–40% by weight of perfluoro(propyl vinyl ether) and has a specific melt viscosity of 0.1×103–110×103 Pa·s (372° C.). The fluorine-containing terpolymer preferably has a comonomer ratio of perfluoro(propyl vinyl ether) to perfluoro(ethyl vinyl ether) of 1.0 or more by weight.
