Abstract
PURPOSE:To provide a title composition with excellent molding processability, product appearance and electroconductivity useful as a permanent anti-static material or the like obtained by compounding carbon black to a mixture with a specific ratio of propylene polymer and high-density ethylene polymer. CONSTITUTION:(i) A propylene (co)polymer (e.g., propylene-ethylene copolymer containing 0.1-5wt% of ethylene) 95-35wt% and (ii) an ethylene polymer with density of 0.945g/cm<3> or more 5-65wt% and (iii) 2-100pts.wt. of carbon black (e.g., furnace black) are compounded to obtain a composition. The mixing is carried out by a method for mixing and kneading three components at once or a method wherein the component (ii) and (iii) are firstly kneaded and, thereafter, the kneaded mixture and a component (i) are subjected to the dry blending and, particularly, the latter blended mixture can be directly subjected to the injection molding. USE:(extremely) High-electroconductive material, a material for preventing electromagnetic wave obstacles.
