A Study of the Comparison of the Effect of Water-Soluble Phthalocyanine on the Relaxation Properties of Latex Polymer in Films and Coatings

The relaxation behavior of an elastic latex polymer has been studied using the method of dynamic mechanical relaxation spectroscopy. The polymer was present in the following forms: as free films and localized on a copper substrate before and after its modification with a water-soluble tetrasodium salt of copper–phthalocyanine–tetrasulfonic acid. The intensity of α-relaxation and the frequency of the vibrational process of the film-forming copolymer has been compared with its thermogravimetric behavior, taking into account the effect of the modifier, which can be localized in the interparticle regions of the latex films and coatings on a copper surface.
