The decomposition of azodiisobutyronitrile (AZDN) has been studied in a simple, robust apparatus specially constructed for simultaneous study of differential thermal analysis and evolved gas detection (DTA/EGD). The results obtained are comparable with those of other thermoanalytic techniques. It is difficult to obtain kinetic results by the DTA technique alone, as the decomposition is confounded with a melting endotherm. This problem does not arise when EGD is used. The apparatus provides a convenient method for research on blowing agents and is being extended to studies of polymer degradation.
