ABSTRACT:
Carbon black compositions comprising ethoxylated esters or polyethers and carbon black. The compositions may be produced by incorporating ethoxylated esters or polyethers onto fluffy carbon black in a pelletizing process to produce free flowing, low dust, attrition resistant carbon black pellets which are easily dispersible in most polymeric systems and impart to polymer compositions enhanced rheological and mechanical properties. The polymeric compositions have particular utility as semiconductive compositions or masterbatch compositions.
