The possibility of using mathematical models of various heterogeneous processes
was considered in order to select the optimal kinetic model for describing the thermal
destruction of studied organoplastics based on LBS-1 according to the experimental
data (tab. 6, 7, fig. 2, 3).
The results of the calculation of kinetic parameters of thermal destruction of stuied
materials (correlation coefficient, minimum of the function, activation energy, pre-
exponential factor) were calculated by the program developed for IBM. They are given
in tab. 8.
