Compounds active as accelerators for curable epoxy and polyurethane systems, those compounds having been prepared by means of a transamination reaction by reacting (a) a substituted phenolic compound (Mannich base) having at least one substituent of formulawherein R1 and R2 are each independently of the other linear or branched C1-4alkyl and R3 is hydrogen, methyl, ethyl or phenyl, with (b) a compound of formulawherein R4 and R5 are each independently of the other C1-C6alkyl or together form a radical of formula -(CH2)5- or -(CH2)2-O-(CH2)2-, n is an integer from 2 to 5 and q is zero, 1, 2 or 3, and the compound obtained or the compounds present in the mixture obtained has/have on average, per molecule, at least one substituent of formulaand the use of those compounds as accelerators in curable systems, preferably in curable epoxy and polyurethane systems.
