Notes:
Poly(ethylene terephthalate) oxidizes on heating at 300°C in an air stream. Various literature has cited crosslinking under such conditions through a butanetriol or a biphenyltricarboxylic acid. In this study gelled polymer was found to contain the latter trifunctional compound, but not the former. In addition, 4,4′-biphenyldicarboxylic acid was found in the degraded gel. There is further indication for the presence of other multifunctional species. All components are consistent with general free-radical arylation mechanisms.
