Abstract
Use of compounds of molecular formula (I) as curing activators of mixes having a cross-linkable unsaturated-chain polymer base: ([R1R2R3NR5(NR4R6R7)n](n+1)+)y (n+1)Xy− (I); where: X is an anionic atom or group; R1, R2 and R3, which may be the same or different, are each CmH2m+1, where m ranges between 1 and 3, or CH2CHCH2 or CHCHCH3; R4, R6 and R7, which may be the same or different, are each CH2CHCH2 or CHCHCH3; n is 0 or 1; y is 1 when n is 1; y is 1 or 2 when n is 0; R5 is an aliphatic group C15-C22 when n is 0; and is an aliphatic group C8-C16 when n is 1; when n is 0, at least one of R1, R2, R3 and R5 comprises a double bond.
