Abstract

PURPOSE: To provide a semiconductive composition having sufficient volume resistivity, excellent adhesive property to insulator and smooth surface by blending carbon black with a predetermined polyethylene having much high molecular weight component, high crystalline property and low melting index.
CONSTITUTION: Under the below mentioned requirements, 5 to 50 part by weight of carbon black and, if necessary, bridging agent are blended with polyethylene having 1.5/10 min. or less of melting index when a predetermined area B in chromatograph measured by gel-permeation chromatography exceeds 15% of area Å of the whole peak; solvent; O-dichlorobenzene, temperature; 140°C, column size; total 6 columns of 107, 107, 106, 105, 104 and 103A, type of columns; polystyrenegel, flow speed; 1ml/min., provided points a,c are respectively ones in which the relative concentration of effluent at the higher and molecular weight sides is zero, and point b represents one at the total length of ac × 0.4 measured from the point a.
