▎ 摘  要

NOVELTY - Polyamide composition comprises (a) at least 40 pts. wt. of polyamide, (b) 0.15-25 pts. wt. of an electrically conductive carbon comprising carbon nanotubes and graphene, (c) 0.3-8 pts. wt. of an oligofunctional compound comprising at least one functional group reactive with reactive groups on a surface of the electrically conductive carbon and at least one functional group reactive with an end group of the polyamide, and (d) optionally conventional auxiliaries and additives, where the sum of the components (a)-(d) is 100. USE - The polyamide composition is useful for producing a molded part (claimed), where the polyamide composition is a polyamide molding composition that is useful in the industrial sectors of automobiles, aircraft and electronics, in communications technology, safety technology and lightweight construction technology, and in instrument switches for explosion-protected rooms, antistatic houses, fuel filters, fuel lines and plug connectors. ADVANTAGE - The polyamide composition improves the dispersion of carbon nanotubes or graphene, and exhibits good conductivity and mechanical properties. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is included for: producing the polyamide composition, comprising reacting the oligofunctional compound with the electrically conductive carbon in the absence of the polyamide, and mixing the reaction product with the polyamide, where optional constituents are added to the mixture during mixing.
