Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing a shaped composite article comprising a polymer composition and carbon particles being carbon nanotubes or graphene, said polymer composition comprising a mixture of a first polymer and a second polymer, and the composite article comprises from 0.01 to 4% by weight of carbon particles based on the total weight of the composite article as determined according to ISO 11358, characterized in that said process comprises the steps of providing a masterbatch comprising the first polymer and at least 5% of carbon particles by weight of the masterbatch as determined according to ISO 11358, providing the second polymer, and blending and shaping, in the same step, the masterbatch and the second polymer in a single extrusion or injection moulding device to form said shaped composite article.
