Abstract The study deals with the diffusion of aqueous acid solutions into diethylenetriamine‐hardened epoxy resins. The results obtained indicate that the diffusion of acids into epoxy resins is affected heavily by the epoxy resin structure, the epoxide group content in the respective resin, and thus also by the molecular mass of the resin concerned. A straight‐line dependence has been found between the diffusion coefficient of acids and the epoxide group contents in the resin.
