The simulation on pyrolysis products of pure PF resin with different chemical structure was investigated and validated by pyrolysis gas-chromatography mass spectrometry (Py-GC/MS). The simulation of pyrolysis products of phenolic resin with different chemical structure was investigated by AMBER (Assisted Model Building with Energy Refinement) force field. The content of pyrolysis products phenol and cresol decreases with the increase of F/P (formaldehyde/phenol) value. The content of pyrolysis products dimethylphenol and trimethylphenol increases with the enhancement of F/P value. The crosslink density of phenolic mixture can be measured by the content of pyrolysis products dimethylphenol and trimethylphenol. Consequently, the results of simulation were validated by the Py-GC/MS experiment.
