Abstract: In this work, the influence of the physicochemical properties of the nonmetallic substrate on the physicomechanical properties of highly elastic carboxyl-containing polyacrylates was assessed. For this purpose, Raman spectroscopy and dynamic relaxation spectroscopy methods were used to study the structure and relaxation behavior of polyacrylate films of different elasticities deposited on a thermosetting polyimide film in the temperature ranges of the elastic properties of the polymer (from –150 to 100°C).
