The polymer material is made from a first monomer and from a second monomer. The first monomer Ar includes at least one aromatic nucleus and the second monomer is a five links conjugated heterocyclic ring. The polymer material has the following general chemical formula: ##STR1## in which: X represents the group constituted by sulphur and selenium; R.sub.1 and R.sub.2 are chosen from the group constituted by hydrogen, and by the alkyl, alkoxyl, and hydroxyl groups; and n is the degree of polymerization. Such materials can be made conductive by adding a doping agent, and they can then be used for manufacturing electrodes, junctions, Schottky barriers, etc.

Polymers containing heterocycles and aromatic nuclei, and conductive

The dielectric spacer between the conductive electrodes of an electrical capacitor is a biaxially oriented film made from a mixture of less than 80 percent by weight of isotactic polypropylene and more than 20 percent by weight of isotactic polybutene-1.
