Ionically curing of VDF-containing fluoroelastomers selected from the ones containing less than 60 moles % of VDF and from the ones containing hydrogenated olefins is improved by using, as accelerators, triazinic compounds of formula: <IMAGE> (I)l, arylalkyl; X=Cl, Br, I, a bisphenoxy radical or O-CH2RF-CH2R2; Rf=a perfluorooxyalkylene chain; R2=-OH, -O-). What is claimed are the fluoroelastomeric compositions containing said accelerators.
