- 1 - Abstract: The invention provides a fluorine-containing copolymer comprising units derived from: (a) tetrafluoroethylene, (b) 8 to 15 % by weight of hexafluoropropene on the basis of the weight of the copolymer, and (c) 0.2 to 2 % by weight on the basis of the weight of the copolymer of a fluoroalkyl vinyl ether of the formula: CF2=CF-O-(CF2)n-CF2X (I) wherein X is hydrogen or fluorine, and n is an integer of 3 to 9. The copolymer has improved stress crack resistance and flex resistance as well as good moldability.
