Dissipative Processes in Filled Acrylate Polymers with Different Elasticities

Abstract—Dissipative processes occurring in filled acrylate polymers in the temperature range from –150 to +150°С are studied in comparison with unfilled systems. It is shown that at positive temperatures dissipative α- and β-processes are characterized by a relaxation mechanism due to a rearrangement of links and segments in the presence of a filler. At negative temperatures, they are characterized by the phase mechanism of the μ‑process due to the formation of different forms of ice and a destruction of the polymer structure during freezing, which are most pronounced in the filled systems.
