Abstract
The present invention relates to a semiconductive polymer composition having easily controllable stripping characteristics, especially for an electric power cable. The semiconductive polymer composition has an ethylene copolymer having polar co-monomer units, wherein the amount of the polar co-monomer units in the ethylene copolymer is 10 wt. % or more, based on the total weight of the ethylene copolymer; an olefin copolymer having propylene monomer units and monomer units of an alpha-olefin having at least 4 carbon atoms, wherein the olefin copolymer has a melting point of 110 ° C. or less, and carbon black in an amount of from 10 to 50 wt. %, based on the total weight of the semiconductive polymer composition, wherein the olefin copolymer (B) is prepared by using a metallocene polymerization catalyst.
