ABSTRACT:
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: ##STR1## (R=H, C.sub.1 -C.sub.4 alkyl; R'=R or benzyl, arylalkyl; X=Cl, Br, I, a bisphenoxy radical or O--CH.sub.2 RF--CH.sub.2 R.sub.2 ; Rf=a perfluorooxyalkylene chain; R.sub.2 =--OH, --O.sup.-). What is claimed are the fluoroelastomeric compositions containing said accelerators.
