Abstract
TGA, DTA, ESR, GLC, IR and mass-spectrometry were used to study the degradation of crosslinked polymers obtained from diglycidyl esters of diphenols and aromatic diamines and the chain nature of both thermal oxidative degradation and thermal degradation was established. NH groups of aromatic amines and products of oxidation are oxidation inhibitors of 2-hydroxypropylene fragments of crosslinked polymer chains. Thermal decomposition of aliphatic radicals formed on crosslinked polymer chains and their interaction with aromatic fragments of the network are the main reactions taking place at T ⩾ 100° in the presence of an amount of oxygen insufficient for the complete oxidation of the polymer.
