The mechanism of the thermal degradation of polystyrene was studied by pyrolysis-gas chromatography and pyrolysis-field ionization mass spectrometry, using a block copolymer of ordinary and perdeuterated styrene [poly(styrene-b-styrene-ds) ]. The main degradation products were monomers, dimers and t

✦ Synopsis
Flash-pyrolyses of two furfuraldehyde resins were performed at 980 and 770 °. The identities of volatile products were established by employing two coupled systems, viz. pyrolysis(gas chromatography)-(mass spectrometry) in electron-impact and chemical-ionization modes and pyrolysis(gas chromatography)-(fourier transform infrared spectroscopy).
