Abstract:

The aim of this work is development of method to determine the conversion of epoxy groups in the epoxy amine resins based on the epoxy oligomer ED-20 and hardener DDM. The studies were carried out in the NIR range. The mathematical division of the spectrum of the resins into individual peaks was used and concentrations of the functional groups were calculated on them. The dependence of the maximum conversion of epoxy groups in the resins after curing at 140 ^оС was obtained.
