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. La présente invention concerne un procédé de préparation d'un article composite mis en forme comprenant une composition polymère et des particules de carbone qui sont des nanotubes de carbone ou du graphène, ladite composition polymère comprenant un mélange constitué d'un premier polymère et d'un second polymère, et l'article composite comprenant de 0,01 à 4 % en poids de particules de carbone sur la base du poids total de l'article composite tel que déterminé selon la norme ISO 11358, caractérisé en ce que ledit procédé comprend les étapes consistant à fournir un mélange maître comprenant le premier polymère et au moins 5 % de particules de carbone en poids du mélange maître tel que déterminé selon la norme ISO 11358, fournir le second polymère, et mélanger et mettre en forme, dans la même étape, le mélange maître et le second polymère dans un seul dispositif d'extrusion ou de moulage par injection pour former ledit article composite mis en forme.
