Paper Title:
Comparative Study of Thermal Degradation Behavior of High Char Yield Phenolic Resin and Commercial Resin
  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 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.
