From the Introduction:'The technique selected for measuring the pyrolysis energy involved the use of the Perkin-Elmer DSC-2 Differential Scanning Calorimeter and TS-1 Thermogravimetric Balane. The TGS-1 also used a Cahn Time Derivative Computer to provide the rate of weight loss simultaneously with the weight loss. All data were taken under a nitrogen atmosphere to preclude oxidation effects. Sample sizes were only a few milligrams, and were deliberately chosen to be small so that heat transfer effects would not interfere with the measurements of energy and mass loss. The materials studied were chosen to provide a basis for predicting pyrolysis energy for materials other than those directly studied and mathematical models were devised to provide for those predictions. A more complete description of the apparatus and procedure is given in Duvvuri's thesis (1974).
