Abstract
An electrically conducting plastic material is produced by blending a polyaniline or a derivative thereof with an organic sulfonic acid or a derivative thereof. A reaction product or blend of a polyaniline or a derivative thereon with an organic sulfonic acid or a derivative thereof can be brought to an easy-to-handle or directly melt-processable form through a heat-treatment process carried out at approx. +40.degree. to +250.degree. C. The obtained plastic material is advantageously further improved by blending the heat-treated reaction product or blend with a thermoplastic polymer and then melt-processing the mixed blend. The properties of the resulting compound material exhibit complete compatibility of the heat-treated reaction product or blend with the thermoplastic polymer.
