FIELD: polymers.
SUBSTANCE: invention relates to technology for making polymeric porous membranes used in electrolytic decomposition of water. Method involves preparing a molding solution based on polysulfone, TiO2 as a hydrophilic filling agent, pore-forming agent and a solvent, molding a membrane on backing, coagulation and the following annealing. Mixture of three similar oligomers and polymers of vinylpyrrolidone or three-four similar oligomers and polymers of ethylene glycol is used as a pore-forming agent. Invention provides creature of chemically stable and mechanically strength membranes used in electrolytic decomposition of water and showing the high specific conductivity, good separating properties with respect to gases O2 and H2, and sufficiently simple and inexpensive method for their making.
EFFECT: improved making membrane.
