    After a short survey of the development of fluorinated elastomers, curing of fluorinated copolymers is described. The discussion includes the main cross-linking agents such as diamines, Schiff bases, dithiols, bisphenols, peroxides, and irradiation, and the modes of action of the agents on copolymers of vinylidene fluoride, chlorotrifluoroethylenes, perfluoropropylene, and perfluoro (methyl vinyl ether). For better understanding the chemistry of cross-linking of fluoro polymers, properties and chemical reactivity of simple polyfluoro compounds are thoroughly discussed with special emphasis on the differences in chemical behavior of polyfluoro derivatives and their parent compounds. Reactions utilized in cross-linking such as addition, displacement, elimination, and isomerizations are exemplified on simple fluorinated compounds, and potential uses of some of them for new types of cross-linking are pointed out.
