ABSTRACT OF THE DISCLOSURE A process for the manufacture of a device compris- ing at least two electrodes and a conductive polymer compos- tion in contact therewith, which process comprises (1) heat- ing a conductive polymer composition to a temperature above its melting point (Tm); (2) heating at least two electrodes, out of contact with the conductive polymer composition; (3) melt-extruding the molten conductive polymer composition from step (1) over the pre-heated electrodes from step (2), the electrodes being at a temperature Te and the conductive polymer being at a temperature Tp when the electrodes and the conductive polymer are first contacted with each other; and (4) cooling the electrodes and the conductive polymer composition; the conditions of the process being such that the electrodes and the conductive polymer composition in contact therewith are at a temperature above Tm for a time which is sufficient to reduce the contact resistance between them and which is less than five minutes.
