Beschreibung
Zusammenfassung:	Described herein is a cable that includes a conductor surrounded by at least one semiconductive layer, wherein the layer comprises a polymer composition comprising a polypropylene homopolymer or a polypropylene copolymer with one or more comonomers, a polyolefin functionalized with an anhydride of a mono- or polycarboxylic acid, wherein said anhydride of a mono- or polycarboxylic acid can be linear or cyclic, wherein the functionalized polyolefin is different from the polypropylene homopolymer or polypropylene copolymer or the second polymer, and wherein the amount of the functionalized polyolefin is up to 10 wt % based on the total amount of the polymer composition, a solid conductive filler and a LDPE homopolymer or a LDPE copolymer of ethylene with one or more comonomers having a melting temperature (Tm) less than the Tm of the polypropylene homopolymer or polypropylene copolymer. Also described herein is a process for producing the polymer composition.
