Annotation The research of the electrical properties of the systems based on polyethylene glycol and carbon nano-tubes near-by the percolation threshold is done using the method of impedance spectroscopy. It is estab-lished that the percolation threshold for these systems is 0,5%, and critical index t  1,17. It is discovered that non-conducting polymeric film appears between separate nanotubes. The thickness of the film which is 7-8 Å and its contact resistance which is 3•105 Ohm were derived using theoretical models. This explains a difference in conductivity of pure nanotubes and probed system after the percolation threshold.
