THE ROLE OF THE MOLECULAR WEIGHT OF POLYVINYLPYRROLIDONE IN THE FORMATION OF TWO-LAYER POLYAMIDE/HYDROGEL MEMBRANES OF INCREASED STRENGTH
The article presents the results of a study of the influence of the molecular weight of polyvinylpyrrolidone on the properties of two-layer hydrogel/polycaproamide membranes. Composite membranes are obtained by the developed method, which consists in the formation of hydrogel membranes with subsequent deposition from a solution into their outer surface of a reinforcing layer based on polyamide modified with polyvinylpyrrolidone.
