Use of compounds of molecular formula (I) as curing activators of mixes having a cross-linkable unsaturated-chain polymer base: ([RRRNR(NRRR)n])y(n+1)X(I); where: X is an anionic atom or group; R, Rand R, which may be the same or different, are each CH, where m ranges between 1 and 3, or CHCHCHor CHCHCH; R, Rand R, which may be the same or different, are each CHCHCHor CHCHCH; n is 0 or 1; y is 1 when n is 1; y is 1 or 2 when n is 0; Ris an aliphatic group C-Cwhen n is 0; and is an aliphatic group C-Cwhen n is 1; when n is 0, at least one of R, R, Rand Rcomprises a double bond.
