The temperature dependence of the heat capacity of polymer compositions based on polyethylene filled with copper nanoparticles was studied. Based on the analysis of the data obtained, a conclusion is made about structural rearrangements. A study of the thermal conductivity of the obtained polymer compositions with nanoscale fillers shows that various components of the filler have a significant effect on the thermal conductivity of the compositions, which is due to the ability of structure formation during their formation. Measurements of the temperature dependence of thermal conductivity and heat capacity indicate the presence of visible structural rearrangements in polymer compositions with metal oxide fillers. There are various methods in which constant temperature transitions of electrical conductivity, thermal conductivity and heat capacity are detected. e. structural restructuring of defective states of polymer compositions. It was found that the transition temperature depends on the degree of filling and crystallinity of the samples.
