Radiation-chemical transformations in poly-ϵ-caproamide and some aliphatic amides

Review on the thermo-oxidative degradation of polymers during processing and in service

“…In aliphatic polyamides carbon-hydrogen bonds of the methylene groups adjacent to nitrogen are the weakest bonds [116,117], causing that most oxidation reactions proceed on these carbons [14,118], although some reactions can take place on methylene groups adjacent to carbonyls of the amide groups too [119]. It was shown that for linear polyamides, the dissociation energy of the most labile hydrogen is independent of the number of methylene groups in their molecule [120].…”

Polymers and TiO2 Based Nanocharges for Bio-Based Composites with Improved Flame Retardancy and Thermal Degradation

“…Secondly, an equilibrium reaction is involved between this polymeric chain and the cotton fiber. Finally, the primary decomposition process is that involving a hydrogen-C-H to nitrogen (N-H) transfer reaction [32][33][34]. This reaction leading to scission of the chain and the evolution of the fragments terminated by chitosan units.…”
