Recently we employed FTIR and Resonant Raman spectroscopy to investigate the chemical constitution of the polymer polyfurfuryl alcohol (PFA) synthetizes in different ways, and appearing macroscopically different: the first one being a liquid and viscous commercial sample, the second one, produced following a thermosetting procedure, being a self-prepared solid and rigid sample.
As a continuation, we have performed a set of temperature dependent Raman spectroscopic measurements in order to study the evolution of these Raman spectra during the glass transition in thermosetted PFA, adopting the same spectral analysis previously performed by us to infer about the glass transition of the polymer poly(methyl methacrylate).
Compatible with Differential Scanning Calorimetry (DSC) data, the Raman spectral features of the thermosetted PFA changed with temperature, this spectral evolution being a clear indication of the PFA glass transition.
