Abstract
The relaxation behavior of a styrene–acrylic latex polymer with a glass-transition temperature of ≤5°C and polymer composites on its basis modified by an indanthrene-type water-soluble dye was analyzed using the method of dynamic mechanical relaxation spectroscopy. The change in the intensity of maximum of dissipative losses of α-relaxation and also of the μ-process is found in polymer films in the negative-temperature range as dependent on the duration and number of their preliminary freezing–thawing cycles at‒30°C taking into account the modifier concentration, which is related to the change in Young’s modulus (modulus defect). Theoretical analysis is performed involving phenomenological model concepts as to the relationship between the vibration-process frequency and Young’s modulus of the polymer material.
