PURPOSE:To provide the electric insulating composition which is used for electric power lines and the like, can prevent antioxidant from being precipitates, and is excellent in heat resistance. CONSTITUTION:The composition is made up of 100 parts by weight polyolefine, 0.01 to 1.0 parts by weight radical generator generating carbon radical and the like, and 0.1 to 2.0 parts by weight antioxidant selected out of at least one antioxidant in thiobis-phenol series, a vinyl group included phenol series, and a thioether series. Antioxidant is grafted to base resin by the radical generator to prevent antioxidant from being precipitated, so that the electric insulating composition excellent in heat resistance can thereby be obtained. |
