Ionic curing, reaction mechanism

FIGURE 5.2 Reaction mechanism for ionic curing. (FromArcella, V. and Ferro, R., in Modem Fluoropolymers, Scheirs, J., Ed., John Wiley Sons, New York, 1997. With permission.) [Pg.97]

The disadvantage of curing fluoroelastomers by ionic mechanism is that dehy-drofluorination required for this reaction produces considerably more double bonds than required for the cross-linking itself. This excess of unsaturation represents weak points in the polymeric chain, which can be attacked by basic substances contained in a contact fluid. This has been actually found when parts cured by this method were exposed to new oil and fuels containing basic additives.19 20 [Pg.96]
