Claims
- 1. A fluorine containing polymer consisting of a copolymer of (1) 3-bromoperfluoropropyl perfluorovinyl ether or 2-bromoperfluoropropyl perfluorovinyl ether, and (2) a fluorine containing monomer of 2 to 8 carbon atoms copolymerizable with said perfluoropropyl perfluorovinyl ether, the content of said perfluoropropyl perfluorovinyl ether in said copolymer being less than 5 mol%.
- 2. The fluorine containing polymer according to claim 1 wherein the fluorine containing monomer of 2 to 8 carbon atoms copolymerizable with the bromoperfluoropropyl perfluorovinyl ether is tetrafluoroethylene, chlorotrifluoroethylene, vinylidene fluoride, hexafluoropropene, pentafluoropropene or perfluoroalkyl perfluorovinyl ethers.
- 3. The fluorine containing polymer according to claim 1 wherein the content of said perfluoropropyl perfluorovinyl ether in said copolymer is 0.01 to 2.0 mol%.
- 4. A curable fluorine containing polymer composition comprising a copolymer [A] of (1) 3-bromoperfluoropropyl perfluorovinyl ether or 2-bromoperfluoropropyl perfluorovinyl ether, and (2) a fluorine containing monomer of 2 to 8 carbon atoms copolymerizable with said perfluoropropyl perfluorovinyl ether, the content of said perfluoropropylvinyl ether in said copolymer being less than 5 mol%, and [B] 0.1 to 10% by weight, based on the copolymer [A] of an organic peroxide.
- 5. The curable fluorine containing polymer composition according to claim 4 wherein the fluorine containing monomer of 2 to 8 carbon atoms copolymerizable with the bromoperfluoropropyl perfluorovinyl ether is tetrafluoroethylene, chlorotrifluoroethylene, vinylidene fluoride, hexafluoropropene, pentafluoropropene or perfluoroalkyl perfluorovinyl ethers.
- 6. The fluorine containing polymer according to claim 4 wherein the content of said perfluoropropyl perfluorovinyl ether in said copolymer is 0.01 to 2.0 mol%.
