ABSTRACT:
As a result of the action of electron acceptors, for example chlorine, bromine and/or iodine, on compositions containing a linear, branched or structurally crosslinked polymer and an unsubstituted or substituted tetrathionaphthalene, tetraselenonaphthalene, tetratelluronaphthalene, tetrathiotetracene, tetraselenotetracene or tetratellurotetracene, electrical conductivity is imparted to the compositions through the formation of charge-transfer complexes. These compositions are suitable for the production of mouldings, filaments, fibres, coatings and composite materials which have an antistatic finish or are electrically conducting.
