NOVELTY – The reactive treatment of polyaniline with acid comprises application of an organic acid or its salt, of high molar weight to polyaniline containing substituent groups or not and initially in powder form. The acid gives over 35 per cent molar doping agent content. EMBODIMENT – The minimum polyaniline unit contains four monomeric rings relative to the doping agent molar concentration. USE – None given.
A26 (Other condensation polymers including silicone polymers and polyimides (mineral silicates and similar materials would not usually appear in Section A).); L03 (Electro-(in)organic – chemical features of conductors, resistors, magnets, capacitors and switches, electric discharge lamps, semiconductor and other materials, batteries, accumulators and thermoelectric devices, including fuel cells, magnetic recording media, radiation emission devices, liquid crystals and basic electric elements. Growing of single crystals of semiconductors and their doping are included, but semiconductor devices, where the manufacture is not claimed are excluded. Electrography, electrophotography, magnetography, electrolysis, electrophoresis, power plant, X-ray and plasma-techniques, ion exchange resins, polyelectrolytes, electroplating, metal electrodeposition, electroforming, anodising, electrolytic cleaning, cathodic protection and electrolytic or electrothermic production or refining of metals are all covered elsewhere (Sections G, J, K and M).); X12 (Power Distribution/Components/Converters)
