Abstract

Described herein are polymer compositions useful as a semiconductive layer suitable for cables. The polymer compositions include (a) a heterophasic copolymer of propylene, (b) a polar copolymer having a polar comonomer having polar groups, (c) a solid conductive filler, and optionally (d) a polyolefin functionalised with a mono- or polycarboxylic acid compound or a derivative of a mono- or polycarboxylic acid compound, wherein said compostion is not crosslinked by the addition of a crosslinking agent. Also described herein is a process for producing the polymer compositions as well as the use of the compositions thereof.
