A mass spectrometric investigation has been performed on the gases evolved during the pyrolysis of natural and some synthetic rubbers over the temperature range 30-4500 It was found that variations in ion ratio with temperature reveal interesting structural information. The ion ratiotemperature prof
Films of a BTDA-mPDA-ODA polyimide copolymer (DuPont Pyralin PI-2555) were spincoated onto silicon wafers and cured at either 300 or 350ยฐC. Films cured at each temperature were then analyzed by various pyrolysis mass spectrometric methods. Low-temperature pyrolysis mass spectrometry showed that poly
