Abstract
A study has been made of the thermal degradation of compounds modelling the structure of network polymers based on diepoxides and aromatic and aliphatic amines. It was found that the thermal degradation of these compounds is an initiated process, and that it takes place by a radical chain mechanism. The temperature of the onset of degradation is higher for the aromatic amine derivatives than for those of the aliphatic amines. This is attributed to the inhibiting action of intermediate radicals emerging in the process of degradation of aromatic amine derivatives. Scission of C βC αN bonds is preferential for all the compounds examined.
