Both analysed resins behave in the same way at higher temperatures. At the 20 oC–50 oC temperature range, it is mainly the intensity of bands associated with C-H bond vibrations that change. A further increase of the temperature causes the structure of the resin to be modified within the range corresponding to furan ring vibrations.
