FIELD: chemistry.
SUBSTANCE: invention relates to technology of obtaining ultrathin polymer fibres by method of electrospinning and can be used for spinning non-woven porous fibrous materials, applied as separating partitions, for instance, for filtration of gases and liquids, for manufacturing diffusion partitions, separators of chemical sources of current, etc. Solution for spinning contains 2.5-4 wt.p. of phenolformaldehyde resin, 2.5-4 wt.p. of polyvinyl butyral, 92-95 wt.p. of ethyl alcohol and as modifying additives 0.02-0.2 wt.p. of tetrabutylammonium iodide or 0.01-0.1 wt.p. of lithium chloride.
EFFECT: invention provides increase of solution electroconductivity, increased output of ultrathin fibres with diameter less than 0,1 mcm.
