THERMOACTIVATION SPECTROSCOPY OF VINYL ACETATE POLYMER FILMS
The article presents the results of the study of polymer films based on a mixture of vinyl acetate copolymer (VA). The mixture
was probed with thermally stimulated depolarization. It is noted that one maximum is observed in the temperature dependences
of depolarization currents obtained for samples with different vinyl acetate content. The results of the calculation of activation
energies corresponding to this process allow us to conclude that an increase in the proportion of vinyl acetate in the mixture leads
to an increase in the dipole-segmental mobility and, as a result, to an increase in the flexibility of the polymer.
