The properties of hydrogel membranes obtained by modification in the volyme
The method of the composite hydrogel membranes synthesis based on the 2-hydroxyethyl methacrylate (HEMA) and polyvinylpyrrolidone (PVP) with simultaneous modification in the volume by the mixture of polyamide-6 (PA-6) and PVP solution with varying the concentration of the reaction mixture in the water has been described in this study. The influence of the water content in the reaction composition on the physical mechanical properties and water absorption of the obtained membranes has been investigated. o
