Relaxation behavior of latex polymers modified by water-soluble dyes. Negative temperature range

详细

The effect of a water-soluble blue indanthrene-type dye on the relaxation structure of styrene–acryl latex with the glass transition point of ≤5°C is studied using the method of dynamic mechanical relaxation spectroscopy. Variation of intensity of the maximum of α-relaxation dissipation losses in the latex polymer is observed, same as its relationship to the mechanism of modification of the polymer film by a dye. Special attention is paid to relaxation effects in the negative temperature range.
