NOVELTY - Composition (C1) comprises: a propylene-olefin-copolymer wax, and a carbon nanotube; where the propylene-olefin-copolymer wax is made of propylene monomers and at least one optionally branched 1-alkylene containing two to twenty carbon atoms (0.1-50 wt.%) based on the total weight of the monomers.    USE - For the production of a conductive polymer or as conductive polymer; as additive in polymers or as polymers, for mechanical reinforcement and for increasing electrical conductivity; as material for use in gas and energy storage; for coloring and as flame retardant; as electrode material or for producing conductor tracks and conductive structures and as emitter in displays; in or as polymer, ceramic or metal composite materials for improving electrical or thermal conductivity and mechanical properties; for production of or as conductive coatings and composite materials; as colorant in batteries, condensers, displays (e.g. flat screen displays) or phosphors; as field effect transistor; as storage medium; in membranes; as catalyst or as support material; in fuel cells; in medical sector and in diagnostic field; in chemical and physical analysis; for production of or as conductive polymers and/or articles made of conductive polymers for use in explosion protection; for production of or as conductive polymers and/or articles made of conductive polymers which can be colored by electrostatic powder coating; for production of or as conductive polymers from which packaging that displays little if any electrostatic chargeability is produced; and for production of or as conductive polymers, preferably conductive polyolefins which are used as bipolar plates in fuel cells (claimed). The conductive polymer is conductive polyolefin, or conductive nanopolyolefin.    ADVANTAGE - The composition is in the form of improved masterbatch, compound or conductive polymer comprising carbon nanotubes (CNTS) as additive, useful for producing conductive polymers and articles, which satisfies demanding requirements such as required viscosity and loading so that required conductivity of the polyolefins can be set; where the current compositions do not satisfy all present-day requirements of industry of very low viscosity in order to give good processability, and high loading i.e. high concentration of CNTs, so that it is possible to set desired conductivity in final articles. The composition, both in the form of a masterbatch or in the form of conductive polymer, has low viscosity which can be obtained at same time as a high loading with CNTs; in particular, a loading of the masterbatch with (up to 20, preferably up to 25, especially up to greater than or equal to 30) wt.% of CNTs can be achieved, without the viscosity becoming so poor that the masterbatch can no longer be produced and processed, or masterbatch not being formed at all. Further, the desired conductivities and desired low surface resistances can be set in conductive polyolefins. The high solids content combined with low viscosity makes inexpensive introduction of additives into the polymer possible; also, the wear on molds is minimized and rapid homogenization and uniform distribution of the CNTs is possible. In the composition, the CNTs are well dispersed, where quality of dispersion is determined qualitatively by optical device on pressed (compression molded) plates or films. The flowability, impact toughness, heat distortion temperature (i.e. temperature of deflection under load) and tensile strength also satisfy requirements.
