Epoxy compositions cured by products of the reaction of aminolysis splitting from the secondary polyethylene terephthalate (PET) and polycarbonate (PC) (household waste) with polyethylene polyamine (PEPA) were studied. The oligomers developed were used as cross-linking agents of an ED-20 epoxy-diane resin for studying its physicochemical properties. The change in viscosity during the curing of thermosetting resin was analyzed, and some its kinetic parameters were found. The thermophysical and mechanical properties of the cured materials were determined, and the optimal content of the hardener in the composition was established. The population of data pointed to the expediency of using the PET and PC household waste to produce oligomers by the aminolysis splitting reaction. The use of them as hardeners can increase the physical and mechanical properties of structural materials. The materials developed have demonstrated improvements in their elasticity parameters, the ultimate strength in static bending and compression, the Brinell hardness, and the shear stress.
