In the present paper the effect of the thermoexfoliated graphite (EG) content (0–0.310 parts by volume), constituent mixing
conditions (a paddle mixer or a disk-and-screw extruder), annealing and aging on thermodestruction processes of polypropylene
(PP)/exfoliated graphite composite materials (CM) by means differential thermal analysis and the thermogravimetric method
have been investigated. The studies have shown that thermodestruction processes in CM based on PP and EG ran in air for expense
of PP thermodestruction. The characteristics of thermodestruction in CM essentially depend on a regime of making and concentration
of components. It is established that processes leading to the formation of less perfect crystalline structures or causing
amorphization of PP (including formation of continuous space structures from EG particles, cluster traps) advances thermodestruction.
The increase in crystallinity extent of PP favors to the decrease in thermodestruction processes.
