Title: NMR study of the carbonization process of furfuryl alcohol resin

Source: Carbon

Year : 1982

Abstract:

Proton CW and pulse NMR studies for furfuryl alcohol resin carbonized over the temperature range 60-860°C are performed. The results are interpreted in terms of structural and chemical changes taking place during heat treatment. Heating up to: 1. (i) 240°C results in an increase in molecular weight and crosslinking; 2. (ii) 320°C produces crosslinking sufficient to form a rigid structure; 3. (iii) 380°C and higher leads to hydrogen release and appearance of paramagnetic centers.
