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. It was established that the molecular weight of polyvinylpyrrolidone, both in the composition of the hydrogel membrane and in the modifying solution, has a significant effect on the interaction between the layers of composite membranes and their characteristics, such as water content, bursting strength , and osmotic salt permeability.
