Abstract
A fluorecopolymer which comprises repeating units (a) based on tetrafluoroethylene, repeating units (b) based on perfluoro(methyl vinyl ether) and repeating units (c) based on perfluoro(propyl vinyl ether) in a molar ratio of (a)/(b)/(c) of 40-70/3-57/3-57. The fluorocopolymer is a perfluoroelastomer which is excellent in low temperature characteristics, heat resistance and chemical resistance.
