Abstract
The thermal degradation behavior of high char yield phenolic resin (PF1.2) synthesized by us was investigated, in comparison with that of commercial resin (PF1.5), using TGA and13C-NMR techniques. It was found that the degradation process of PF1.2behaved very similar to that of PF1.5during heat treatment up to 700 °C under N2atmosphere, but resulted in a somewhat different extent of some specific reactions. That was, although the reactions occurring up to 700 °C were dominated by crosslinking and/or polyaromatization, fewer methyl bonds from breaking of methylene bridges were formed in PF1.2than in PF1.5. As a consequence, a higher char yield of 73.8% of PF1.2than that of PF1.5(57.5%) up to 700 °C under N2atmosphere was attached, with better thermal properties.
