A composition comprising a matrix of a thermoplastic, thermosetting or a structurally crosslinked polymer, in which is incorporated an electroconductive network of crystal needles of a charge transfer complex (abbreviated to CT complex) from an electron donor and an electron acceptor, characterized in that: (1) the matrix contains uniformly distributed an excess, with respect to the CT complex formation, either of at least one electron donor or at least one electron acceptor as weakly polymer-soluble finely divided particles, (2) the CT complex is formed either by at least one weakly polymer-soluble electron donor and at least one polymer-soluble electron acceptor or by at least one weakly polymer-soluble electron acceptor and at least one polymer-soluble electron donor, and (3) the crystal needles growing from the weakly polymer-soluble particles are formed in the polymer mass as microcrystalline needles, which are in contact and connect the weakly polymer-soluble particles, thus forming a network which penetrates the polymer mass. The electroconductive composition of the instant invention can be advantageously applied as electroconductive articles, as electroconductive composites and, in particular, as transparent antistatic films. |
