Abstract
The invention comprises a thermoplastic elastomer blend which is composed of a) about 10-90 w-% of a thermoplastic elastomer component which is chosen from the following ones: a styrene block copolymer of the type A-B-A, where A stands for a polystyrene block and B stands for a soft or elastic polymer block; a blend of an olefin homopolymer or olefin copolymer with a thermoplastic or crosslinked elastomer, and b) about 90-1 w-% of an inherently electrically conductive polymer component comprising polyaniline or its derivative which has been doped by a protonic acid.
