ABSTRACT:
Antistatic or electrically semiconducting thermoplastic polymer blends contain two partially compatible thermoplastic polymers A and B, whereof polymer A has a lower viscosity than polymer B and whereby the solubility parameters thereof also differ. Polymer A, which forms the continuous phase, contains an addition of electrically conductive substances and forms current-carrying conductor tracks. The polymer blends are suitable for producing antistatic or electrically semiconductor coatings, foils, moulded articles or parts.
