Abstract
The method and results of direct analysis of complex primary kinetic data on the exothermic decomposition of condensed materials without involving the differential form of the kinetic equation are con- sidered. Using the example of data for the thermal decomposition of picric acid, widely used in composite ma- terials, including polymer ones, the effectiveness of the method and the good correspondence of the results ob- tained with the literature data are shown.
