摘要：

A comparison was made of the physicochemical and physicomechanical properties of films and coatings based on latex polyacrylates before and after their modification water-soluble tetrasodium salt of copper-phthalocyanine-tetrasulfonic acid. Using atomic-force microscopy methods, Raman spectroscopy and thermogravimetry showed that phthalocyanine is localized on the surface of latex particles in the interparticle regions of films and coatings due to interaction between phthalocyanine and polyacrylate. Using the method of dynamic mechanical relaxation spectroscopy, an increase in the intensity of alpha-relaxation was established upon modification of polymer films as a result of disruption of the relaxation homogeneity of the polymer material. Adhesion of unmodified and modified polymers to a metal substrate causes a decrease in the intensity of alpha-relaxation and frequency of the oscillatory process. Modification of the polymer and its adhesion to the substrate are accompanied by a decrease in its elasticity.
