Beschreibung
Zusammenfassung:	The present invention relates to the use of a free radical initiator composition for the reduction of gels in polyethylene materials wherein a polyethylene material is subjected to melt processing in the presence of a free radical initiator composition characterized in that the free radical initiator composition is added in quantities ≤0.050 wt % compared to the total weight of the polyethylene material. Such use results in polyethylene materials having reduced gel content, whilst still having good optical and mechanical properties, and whilst preferably maintaining melt properties such as melt mass flow rate.
