ELECTRICALLY SEMICONDUCTIVE POLYOLEFIN MIXTURE

摘要

PURPOSE:To obtain an electrically semiconductive mixture having excellent smoothness, by mixing a polyolefin mixture contg. electrically conductive carbon black dispersed therein with a polyolefin. CONSTITUTION:An electrically semiconductive mixture is obtd. by mixing a polyolefin mixture contg. electrically conductive carbon black dispersed therein with a polyolefin. It is preferred that electrically semiconductive carbon black is dispersed in the polyolefin during the course of polymn. and the resulting polyolefin mixture is blended with a polyolefin which is the same kind or a different kind of the polyolefin for the mixture. Pref. carbon black is used in an amount of 5-60wt% based on that of the polyolefin mixture. The amount of carbon black in the electrically semiconductive polyolefin mixture of the polyolefin mixture and the polyolefin is pref. 2-40wt% from the viewpoint of the smoothness of the resulting electrically semiconductive layer.
