Abstract
The present invention relates to a method for the manufacture of a polymer composition comprising polymer and carbonaceous filler comprising the steps of: a. introducing a first portion of polymer and a first portion of carbonaceous filler into a first feed section of an extruder, b. introducing a second portion of polymer and optionally a second portion of carbonaceous filler into a second feed section located downstream of the first feed section of the extruder, and c. extruding the resulting polymer composition; wherein the polymer composition comprises 0.01 to 3 wt. % of the carbonaceous filler relative to the total weight of the polymer composition.
