The use of a computer-controlled temperature-programmable platinum filament as a probe for linear programmed thermal degradation mass spectrometry Is reported. A study of time-resolved pyrolysis of various polystyrene samples and of poly(vinyl chloride) was made: results show a stepwise thermal degradation process. Energies of activation and preexponential factors for these thermal degradations were determined.
