Abstract

Abstract 1. Antistatic or electrically semi-conductive thermoplastic polymer blends based on organic polymers, electrically conductive substances and the usual additives, characterized in that, they contain two partially compatible thermoplastic polymers A and B, of which polymer A at a given temperature has a lower melting viscosity in comparison to polymer B and between which there is a solubility-parameter difference of approximately 0.3 to 1.5 (cal/cm**3 )**1/2 , in which the polymer A, which forms the continuous phase, essentially contains the electrically conductive substances.
