摘要

FIELD: chemistry.;SUBSTANCE: invention deals with elaboration of a photopolymerised composition for obtaining a polymer material, which possesses the three-dimensional nanoporous structure with hydrophobic surface of pores, a single-stage method of its obtaining and the porous polymer material with selective sorbing properties and a single-stage formation based on it water-separating filtering elements with the specified geometry and required mechanical strength, applied in devices for purification of organic substances, mainly hydrocarbon fuels, oils, oil products, from emulsified water and mechanical admixtures. The photopolymerised composition contains oligoetheracrylate, a light-sensitive component, as such used is 1,1,7-trimethylbicyclo[2.2.1]heptanes-2,3-dione (camphorquinone) or ortho-quinone or their mixture, a reducing agent, for instance, amine, a functionalising monomer of vinyl series, solidified in accordance with the radical mechanism, less reactionable in comparison with oligoetheracrylate and a forming hydrophobic polymer, and a non-capable of polymerisation component, dissolving composition monomers and compatible in a restricted way with the final polymer. The method of the single-stage obtaining of the polymer nanoporous material with the functionalised surface of pores, as well as methods of the single-stage obtaining of products, water-separating filtering elements with the specified geometry and increased mechanical strength, is elaborated on the basis of the composition.;EFFECT: nanoporous polymer water-separating filtering elements with the specified geometry and increased mechanical strength have been for the first time obtained by the single-stage photopolymerisation method; selectively sorbing properties of filtering elements have been experimentally proved at the example of purification of benzene from water.;15 cl, 1 tbl, 8 dwg, 6 ex
