Abstract
This invention relates to a fluorine containing polymer as well as a curable composition containing the polymer and an organic peroxide. The fluorine containing polymer consists 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 %.
