Abstract
The paper presents the results of a study of the effect of temperature and concentration of thermal ash nanoparticles 10–40 wt % on the regularity of changes in thermomechanical curves measured with a Kanavets apparatus. The influence of the concentration of the crosslinking agent dicumyl peroxide on the first-order phase transition and the temperature range of the hyperelastic and viscous-flow states has been studied. It is shown that with the introduction of 0.5 wt % of dicumyl peroxide, all three physical states are preserved in the polymer: solid, hyperelastic, and viscous-flow. With an increase in the concentration of dicumyl peroxide to 1.0–2.0 wt %, the crosslinked samples pass into a glassy state after the softening temperature.
