FIELD: manufacture of polymeric membranes. SUBSTANCE: membranes are based on hydrophilic polymers. They are made by applying polymer solution preliminarily heated up to 30-40 C to molding surface, holding at this temperature for 60-120 min in humid air containing 80-95% of moisture, coagulation in settler at temperature of 40- 60 C. EFFECT: higher selectivity and permeability of polymeric membranes. 1 tbl
