The structure and properties of the intermolecular polycomplex, formed by cooperative intermolecular hydrogen bonds between poly(vinyl alcohol) and poly(acrylamide), were investigated. By viscometry, gel chromatography and differential scanning calorimetry the characteristic composition of polycomplex was established. The compatibility of polymers and structural peculiarities of polycomplex in a block state were characterized. Due to computer processing of the polycomplex IR spectra in amide I, amide II region by the spline method, the presence of the absorption band at 1668 cm-1, related to hydrogen bonds between polymer pair, was shown. The developed hydrophobic regions in polycomplex structure in water, which additionally stabilize the polycomplex particles, were detected. The structure of such intermolecular polycomplexes is proposed.
