    摘要： A novel fluorine-containing copolymer is obtained by radically copolymerizing 60 to 80% by mole of ethylene and 20 to 40% by mole of hexafluoropropylene in the presence of 0.1 to 15% by mole of tetrafluoroethylene as a comonomer, each based on the monomer mixture, under pressure of 10 to 40 kgf/cm.sup.2. A fluoroelastomer is obtained by curing the obtained copolymer. The copolymerization is carried out under mild conditions, and the fluoroelastomer obtained by curing the resulting copolymer is excellent in amine resistance.
