Matrix-assisted laser desorption/ionization-time-of-flight/time-of-flight collision-induced dissociation study of poly(p-phenylenediamine terephthalamide) fragmentation reactions

- This represents the first derailed MS/MS study of aramid polymers.
- MALDI-TOF/TOF collision-induced dissociation experiments are reported on model PPD-T polymers.
- Diamine-terminated oligomers were the major product of synthesis using excess amine.
- Di-carboxylic acid oligomers were the major product for excess acid.
