In conclusion, the analysis of raw PBPAC identified characteristic polymer responses for each analytical method, with results similar to those described by the supplier or in other literature studies. This can serve as a basis for our next steps, with any change in the responses obtained being taken as an indication that degradation has taken place, the most expected ones being a shift in the molecular weight distribution observed in SEC, as well as the appearance of new peaks in FT-IR, 1 H NMR and MALDI-TOF.
