Abstract

This paper reports an investigation of the oxidation of three epoxy-amine networks obtained from DGEBA cured with three sorts of aliphatic hardeners ethylene diamine (EDA), diethylene triamine (DETA), and triethylene tetraamine (TETA). Oxidation was monitored by FTIR with an innovative discussion of CH₂ consumption. Methylene groups held by hardeners groups were shown to be more sensitive to oxidation, which was confirmed by a discussion of Bond Dissociation Energies (BDE) computed by a machine-learning approach.
