Composition of polyamides with low concentration of carboxamide groups and electrically conductive carbon

A polyamide composition comprising the following components: a) at least 40 parts by weight of a polyamide whose monomer units contain an arithmetic average of at least 7.5 carbon atoms, b) 0.1 to 15 parts by weight of at least one salt with a non-metallic cation, c) 0.1 to 25 parts by weight of at least one dispersant based on esters or amides and d) an electrically conductive carbon selected from the group of carbon black, graphite powder, carbon fibers, carbon nanotubes and/or graphene, in an amount which results in a specific surface resistance of the polymer composition to IEC 60167 of 10−1 to 1010Ω, e) 0 to 5 parts by weight of at least one metal salt, and optionally f) customary assistants and additives, where the polyamide of component a) is not a PA12 if carbon nanotubes are present as component d), and where the sum of the parts by weight of components a) to f) is 100, can be used for production of mouldings with improved electrical conductivity and improved surface quality.
