Mechanism of the Dicyandiamide/Epoxide Reaction
Macromolecules
(1991)
Abstract
A mechanism is proposed for the dicyandiamide (dicy) cure of epoxy resins based on the
analysis of products formed by the reaction of a monofunctional epoxide with dicy and with cyanamide.
Products were isolated from the uncatalyzed reaction mixtures using preparatory liquid chromatography and
were characterized by FTIR, NMR, mass spectrometry, and elemental analysis. Both linear dicy/epoxide
adducts and cyclical species were identified and the mechanism of the cyclization reaction was delineated.
A mechanism for carbonyl generation during the later stages of cure was also found.
