Pyrolysis-Gas Chromatography/Mass Spectrometry of Thermoplastic Polymers
Abstract
Thermal degradation mechanisms of ten thermoplastic polymers have been investigated using pyrolysis-gas chromatography with mass spectrometric and flame ionization detection. The results indicate that an unknown plastic can be identified on the basis of its degradation products and that interpretation of the degradation product analysis can be used to predict thermal degradation mechanisms and chemical structures of polymers. Identification of thermal degradation products gives in into the hazards involved with these materials in the presence of heat and flame. Pyrograms of ten thermoplastic polymers including polyethylene (HiFaxTM), polymethylmethacrylate (PlexiGlasTM), polyphenylene either (PrevexTM), polyacetal (DelrinTM), polyamide (Nylon 6,6TM), polyphenylene sulfide, polyvinylchloride (BoltaronTM), polyimide (SolimideTM), polyamideimide (TorlonTM), and polyetheretherketone (VictrexTMPEEK) obtained at 800 C and 1000 C with both flame ionization detection and quadrupole mass spectrometric detection are included. Keywords: Pyrolysis gas chromatography, GC MS Gas chromatography, Mass spectrometry, Thermoplastics, Degradation, Mechanisms, Analysis, Canada.
