Abstract

A method produces a polymer composition with improved DC electrical properties. A cable can be surrounded by at least one layer that includes the polymer composition. The polymer composition includes a polyolefin, and the polymer composition has an electric conductivity of 0.50×10−15 S/m or less, when measured according to DC conductivity method using a tape sample consisting of the polymer composition.
