<p>The invention relates to an electrically conductive elastomer composition which comprises a thermoplastic polymer and a doped aniline polymer. A problem in the preparation of electrically conductive elastomer compositions is the lack of thermoplasticity of the electrically conductive component, making difficult the processing and the obtaining of a homogenous product. This problem has now been solved by having the doped aniline polymer be a substantially thermoplastic doped aniline polymer which is obtained by reacting with a functionalized protic acid a conjugated homo- or copolymer made up of at least unsubstituted and/or substituted aniline mers. The protic acid functionalizes the aniline polymer either on being heated together with the aniline polymer to a temperature of 80-250 °C or on being heated together with the aniline polymer and a solvent and on the solvent being evaporated. The elastomer composition is also composed of a plasticizer which plasticizes the doped aniline polymer and promotes its flow, preferably a metal compound with a plasticizing effect, such as a reaction product of zinc oxide and dodecylbenzenesulfonic acid.</p> |
