Abstract
The kinetics of curing epoxyurethane oligomer PEF-3A by curing agents of different chemical nature has been studied by differential scanning calorimetry. The reactivity of PEF-3A has been found to be higher than that of epoxide resins owing to the polar urethane groups in its molecule. The strength of the adhesive joint has been shown to increase after modification of PEF-3A-based compositions by orthophosphoric acid.
