Abstract
The paper presents the study results of the molecular weight effect of polyvinylpyrrolidone (PVP) on the properties of composite hydrogels/polycaproamide membranes, which were obtained by modifying hydrogel films based on copolymers of 2-hydroxyethylmethacrylate (HEMA) with PVP by applying ultra- thin layers on the basis of a polyamide (PA-6) with PVP mixture. It was found that the interaction magnitude between the layers of composite membranes, as well as their properties – water content, tensile strength, salt and water permeability coefficients, largely depend on the molecular weight of PVP as in the original polymer-monomer composition and in the modifying PA-6/PVP solution.
