Abstract
Abstract An electrically conductive polymer, doped with at least one electron acceptor or electron donor, which polymer has a main chain of arylene units and interspersed regularly or irregularly between them one or more chalcogen atoms or groups of such atoms, especially sulfur and/or oxygen atoms; especially poly(p-phenylene sulfide) doped with an arsenical doping agent. These doped polymers have utility similar to semiconductors or to metals, particularly where light weight is desired, for example in battery electrodes.
