FIELD: chemistry.
SUBSTANCE: invention can be used to produce a waterproof, air-vapour-permeable membrane, as well as to regulate the complex of performance properties of a membrane material. The composition includes, wt %: polyacrylonitrile 7-9, polyvinylidene difluoride 9-11, the rest - N,N-dimethylacetamide and N,N-dimethylformamide at a ratio of 1:1.
EFFECT: invention makes it possible to increase the functional properties of membranes, namely the water resistance and the speed of electroforming.
