摘要：

The spectral changes of Crystal Ponceau 6R and Ponceau 4R induced by the interaction with polycations having N,N-dimethyl-2-hydroxypropane-1,3-diylammonium chloride units in the main chain were followed. The stoichiometry of the polycation-dye complex related to the dye structure was elaborated by UV-VIS spectrophotometry and viscosimetric measurements. Formation of a tricomponent complex between the polycation/dye complex and poly(sodium acrylate) was also revealed.
