A mechanistic study of the reaction between furfural-acetone resins and polyamines

We have studied the reactions of furfural-acetone resins and their main components, i.e., monoand difurfurylidene acetones, with aliphatic polyamines and organic acid anhydrides. It is shown that furfural-acetone resins can be hardened under the action of polyamines and do not react with acid anhydrides. probable mechanism of the reaction with polyamines is proposed.
