A TG/FTIR study on the thermal degradation of poly(vinyl pyrrolidone)

The aim of this study was to gain some fundamental knowledge on the thermal degradation pathways of poly(N-vinyl pyrrolidone) using Thermogravimetry coupled with Fourier Transform Infrared Spectroscopy (TG–FTIR) in addition to IR and 1H NMR spectroscopic studies of the partially degraded samples. It...
