Phenolic resins Part 6. Identifications of volatile organic molecules during thermal treatment of neat resols and resol filled with glass fibers
Résumé
The physicochemical characterization of resols before and after cross-linking in the presence and absence of fiberglass was carried out using spectroscopic and chromatographic techniques. Experiments involving gas chromatographic thermodesorption coupled with mass spectrometry (GC-MS) led to the identification of the different volatile organic compounds present during the heat treatment of neat resol and resol filled with glass fibers. The results show that the knowledge of initial resol structures are very important data for kinetically following the departure of volatile compounds during resol manufacture.
