Abstract: A simulation mathematical model is presented that describes the process of vitrification and devitrification of the binder. Theoretical estimates of the effective physical and mechanical parameters of the material and microstructural stresses with temperature change are obtained. A numerical scheme has been developed (in the form of a computer program) that makes it possible to implement the modeling technique. Estimates of elastic moduli and submicrostructural stresses are obtained. The results can be used to select the composition of the material and its parameters at the final stages of the technological process of creating a polymer binder.

Keywords: thermoplastics, vitrification, relaxation transitions, “frozen” deformations.
