Abstract

L'invention concerne l'industrie du matériel électrique. Elle a pour objet une composition polymère conductrice qui comprend un copolymère cristallin forme d'unité dérivant d'au moins une oléfine et d'au moins 10 % en poids d'unités dérivant d'un comonomère oléfinique comprenant un radical polaire et, en dispersion dans ce copolymère, un noir de carbone conducteur d'une granulométrie supérieure à 18 millimicrons d'une équidistance d de plus de 360 et d'une surface spécifique A judicieuse. Ces compositions polymères sont préférées pour la fabrication d'appareils de chauffage autorégulateurs.
