FIELD: chemistry.SUBSTANCE: invention relates to chemical industry and nanotechnology. According to one embodiment, carbon material (I) containing single-wall carbon nanotubes and not less than 50 % of carbon is reacted with solution of iron chloride with concentration of not less than 0.1 M. According to another embodiment, carbon material (I) containing single-wall carbon nanotubes and 0.5–50 wt. % of iron oxide impurities is reacted with a solution of hydrochloric acid having concentration of not less than 0.1 M at temperature not lower than 40 °C. In both embodiments, the obtained wet carbon material is then separated and heat treated. Carbon material (I) is obtained by oxidising carbon material (II) containing single-walled carbon nanotubes and 0.3–40 wt. % impurities of phases of nanosized iron and metallic iron, in gas stream containing molecular oxygen and water vapor, at temperature not lower than 300 °C. Ratio of integral intensities of G-mode and D-mode of Raman spectrum of light with wave length of 532 nm on carbon materials (I) and (II), respectively, not less than 2 and not less than 50. Produced carbon material, modified with chlorine, containing single-walled carbon nanotubes, most of which is part of percolation network, contains not less than 90 wt. % of carbon and not less than 3 wt. % of chlorine. Said carbon material is introduced into the polymer material into a reaction mixture which participates in the polymerisation or polycondensation reaction to form a polymer material or into one of the components of said reaction mixture. Polymerisation reaction is carried out under ultraviolet radiation and/or at temperature not lower than 60 °C. Obtained composite polymer material has specific electric resistance not higher than 10Ohm⋅m and contains not less than 0.001 wt. % of said carbon material, modified with chlorine, containing single-wall carbon nanotubes.EFFECT: invention can be used in making composite polymer materials.23 cl, 7 dwg, 1 tbl, 23 ex
