✦ Synopsis


Proton CW and pulse NMR studies for furfuryl alcohol resin carbonized over the temperature range 60-86O"C are performed. The results are interpreted in terms of structural and chemical changes taking place during heat treatment. Heating up to: (i) 240°C results in an increase in molecular weight and crosslinking; (ii) 320°C produces crosslinking sufficient to form a rigid structure; (iii) 380°C and higher leads to hydrogen release and appearance of paramagnetic centers.
