Perfluoro(methyl vinyl ether) is a widely known monomer used in the industrial scale, particularly, in the production of fluorine containing rubbers. The known values of copolymerization constants of perfluoro(methyl vinyl ether) (?1) with tetrafluoroethylene2 (?2) are r1 = k11/k12 = 0.22 and r2 = k22/k21 = 1.42 (index 2 concerns tetrafluoroethylene).
Perfluoromethyl vinyl ether as the special fluoric monomer has wide applications in the development of new-style fluoro plastics and fluoro rubber with excellent integrative properties.
There are five main types of FKMs, determined by the types of monomers used to produce the fluoroelastomer. These include Vinylidene Fluoride (VF2), Hexafluoropropylene (HFP), Tetrafluoroethylene (TFE), Perfluoromethylvinylether (PMVE).
