Article Preview

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 and 13C-NMR techniques. It was found that the degradation process of PF1.2 behaved very similar to that of PF1.5 during heat treatment up to 700 °C under N2 atmosphere, 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 PF1.2 than in PF1.5. As a consequence, a higher char yield of 73.8% of PF1.2 than that of PF1.5 (57.5%) up to 700 °C under N2 atmosphere was attached, with better thermal properties.
