The novel heterocyclic multifunctional amine adduct of the present invention is the reaction product of at least one aromatic or aliphatic polyamine compound having at least two amine groups, which are separated by no more than one carbon atom, with at least one carbonyl-containing compound selected from the group consisting of aldehydes and ketones.
Suitable aldehydes correspond to the formula: ##STR7## wherein R represents: an alkyl group of one to twenty carbon atoms, which may be branched or unbranched, and which may be unsubstituted or substituted with an aldehyde group (--CHO) or a carboxyl group (--COOH); an aromatic residue, preferably a phenyl group, which may be unsubstituted or substituted with an aldehyde group, a hydroxyl group or a lower alkoxy group of one to five carbon atoms.
Examples of such aldehydes are terephtalaldehyde, glyoxal, glutaraldehyde, glyoxylic acid, salicylaldehyde, vanillin and o-vanillin and heptaldehyde Suitable ketones correspond to the formula: ##STR8## wherein R.
sub.
1 and R.
sub.
2 independently represent: an alkyl group of one to twenty carbon atoms, which may be branched or unbranched, whose chain may be interrupted by one or more carbonyl groups ##STR9## an aromatic residue, preferably phenyl; or R.
sub.
1 and R.
sub.
2 may together form a cycloaliphatic ring may be interrupted by a carbonyl group; or R.
sub.
1 and R.
sub.
2 may together form an O-heterocyclic ring which may be substituted with lower alkyl group of one to five carbon atoms, hydroxyl group or acetyl group.
Examples of such ketones are 2,4-pentanedione; 2,3-butanedione; benzil; 1,3-cyclohexanedione; acetone; 2-butanone; 2-heptanone; dehydroacetic acid and acetophenone
