ABSTRACT:
Dehydrogenated polycyclopentadiene which is insoluble in organic solvents, has a specific conductivity of at least 10.sup.-7 S.cm.sup.-1 and contains essentially the recurring structural units of the formulae III to VIII ##STR1## in which X.sup.- is an anion derived from iodine or a metal pentahalide or metalloid pentahalide, is obtained by treating polycyclopentadiene with iodine or a metal pentahalide or metalloid pentahalide and can be used as an electrically conducting material for the production of, for example, conductors, electrodes, batteries or semi-conductors, components.
