Abstract
Based on an analysis and generalization of the results of theoretical and experimental studies of the basic laws of physicochemical transformations that occur in highly filled elastomers upon heating, a differential mathematical model of the kinetics and energy of the pyrolysis process of these materials is formulated. A distinctive feature of the model is the inclusion of changes in the composition of the material during heating to high temperatures, as well as the influence of the heating rate on the process parameters. The results of numerical studies are in satisfactory agreement with experimental data.

Notes
In experimental studies of the pyrolysis of highly filled elastomers, O.S. Vodolazsky, G.G. Konkina and G.V. Malkov took part.
Near temperature T*, the processes of chemical and phase transformation merge into a single, one-stage process of the chemophase transformation of the polymer, accompanied by the initial transfer of sufficiently large blocks (oligomers) into the gas phase and the course of further destruction reactions already in it [15, 16].
In experimental studies of the behavior of a typical rubber-like material when heated under pressure A.N. Garashchenko, V.F. Kablov, and V.G. Kochetkov [17].
Hereinafter, for the corresponding parameters, we use the notation adopted in [10].
