FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of highly molecular compounds, nanotechnologies and photochemistry and deals with elaboration of photo-solidificated composition for obtaining polymer material, possessing three-dimensional nanoporous structure with hydrophobic surface of pores, single-stage method of its obtaining and porous polymer material with selective sorptive properties and single-stage formation on its basis of water-separating filtering elements with specified geometry and required mechanical strength, applied in devices for purification of organic liquids, mainly hydrocarbon fuels, oils, oil products, from emulsified water and mechanical admixtures. Photopolymerising composition contains oligoetheracrylate, photoinitiator, as photoinitiator, used is ortho-quinone with condensed aromatic system, functionalising monomer of vinyl series, solidified by radical mechanism, less reactionable in comparison with oligoetheracrylate and forming hydrophobic polymer and non-polymerisationable component, dissolving composition monomers and limitedly compatible with final polymer. On the basis of composition developed is method of single-stage obtaining of polymer nanoporous material with functionalised surface of pores, as well as methods of single-stage obtaining of products - water-separating filtering elements with specified geometry and increased mechanical strength. Nanoporous polymer material, selective sorptive properties of which have been experimentally confirmed, is obtained. Selectively sorptive properties of filtering elements have been experimentally proved on the example of benzene purification from water.

EFFECT: nanoporous polymer water-separating filtering elements with specified geometry and increased mechanical strength have been obtained by single-stage method for the first time.
