Abstract
The invention relates to the preparation of an electrically conducting plastic material by bringing together polyaniline or a derivative thereof and an organic sulphonic acid or a derivative thereof. The usual product is poorly defined, dirty, very corrosive and difficult to handle. Its processing in the molten state by itself or together with a thermoplastic polymer is only possible if a separate treatment with a solvent is included, which however limits the type of product obtained by the processing to films or fibres, from which the solvent can be removed by evaporation. In the process according to the invention, however, the said reaction product or a mixture of polyaniline or a derivative thereof and the organic sulphonic acid or a derivative thereof is brought into a form that is easy to handle and process as a melt by heating it to 100-250 degrees C. The heat-treated reaction product or mixture is further treated preferably by mixing it with a thermoplastic polymer and by processing it in the molten state to form a combined product. The latter shows that the heat- treated reaction product or mixture and the thermoplastic polymer are fully compatible and can be readily combined with each other.
