An examination was made of the influence of the complexing medium on the structure and particle size distribution of interpolymer complexes. The chemical composition of polycomplexes was analysed as a function of the complexing medium. For the case of a polyacrylic acid–polyvinyl alcohol complex obtained in a glycerin–water medium, the results of differential scanning calorimetry, thermogravimetric analysis, analysis of the deformation and strength properties and sorption characteristics, a series of successive qualitative reactions on glycerin, and also data of IR spectroscopy show the possibility of the formation in the given binary solvent of polycomplexes containing glycerin in their structure.
