The thermophysical properties of polymeric materials filled with the refractory compounds titanium carbide (TiC) and ferrite (Fe 3 C) were studied using thermogravimetric and differential thermal analysis. These techniques allow structural transformations in modern materials to be assessed. Composites containing an active additive at a concentration of q = 0.100 wt% exhibit the lowest relative mass loss ( ε m = 65.3%), due to the formation of a significant number of bonds between the polymer components and redistribution of thermal energy within the polymer volume. Comprehensive studies of the thermal stability parameters ( T i , T f i n , T max , and T 0 ) established the course of physicochemical processes during the thermal degradation of filled composites. The activation energy increased by 1.2 times. The thermal stability of the developed polymers containing 0.100 wt% particles of the synthesized iron/TiC mixture increases from 587 K to 612 K. The rational introduction of the filler into the polymer matrix increases the stiffness of the segments and the main chain due to the presence of TiC (20%) and Fe 3 C (5%), which are formed after high‐voltage electric discharge (HVED) synthesis. The active particles of refractory compounds serve as centers for the formation of an additional spatial polymer network, ensuring the redistribution of thermal energy within the polymer volume. It has been proven that the key parameter affecting the permissible temperature range of the developed polymers is the initial exoeffect temperature (Ti), which is 485.4 K.
