The route chosen for modification of the sorption capacity of N -polyvinylpyrrolidone (PVP) was stabilization of its polymer skeleton by the action of intermolecular hydrogen bonds. The secondary supermolecular formations were regulated by introduction into aqueous solution polyvinylpyrrolidone at room temperature of substances containing active groups tending to form intermolecular H bonds with electron donors-oxygen atoms of carbonyl groups in PVP. Figures show IR absorption spectra of aqueous solutions of PVP, and dependence of the conductivity of aqueous solutions. It was concluded that preliminary addition both of monomeric and polymeric compounds, causing fromation of H bonds in the system, to PVP solutions causes significant changes in the structural organization of the PVP macromolecular chains, as the result of which the polymer acquires high sorption capacity for iodine.
