The relaxation behavior of polymer compounds based on latex polymers and water-soluble modifiers with different chemical structures are studied by dynamic mechanical relaxation spectroscopy. The revealed changes in the intensity of dissipated losses of the α-relaxation process in the internal friction spectra of polymers depending on the modifier nature are compared with the Young’s modulus (the defect of the modulus) and the morphological features of the polymeric system. The phenomenological models are used to conduct a theoretical analysis of the association between frequency of the oscillatory process and the Young’s modulus of the polymer material, as well as to analyze the relaxation heterogeneity evaluated according to the width of the continuous spectrum of relaxation time in normalized coordinates λ/λ max versus {( Т  – Т max )/ Т max }.
