Summary
The mechanism of the epoxy resin curing with dicyandiamide was studied using the model phenyl glycidyl ether and different substituted dicyandiamides. Some reaction products were isolated by HPLC and characterized by FTIR and Carbon-13 NMR spectroscopy. A reaction pathway is proposed discussing the formation of cyclic structures, carbonyl groups and oligomerization products of the glycidyl ether.
