Аннотация:The effect of a water-soluble indanthrene blue dye on the relaxation structure of styrene-acryl latex polymer with the glass-transition point below 5 degrees C is studied in a frost-resistant aqueous-dispersion coat using the method of dynamic mechanical-relaxation spectroscopy. A significant difference is found between the change in the intensity of the maximum of alpha-relaxation dissipative losses of a latex-polymer binder in the ground coat and in free latex polymer when they are modified by a blue dye, which is due to the ground-coat composition. Special attention is paid to relaxation effects in the negative temperature range.
