Abstract
The present invention relates to a use or process for the reduction of gels in polyethylene materials comprising at least one ethylene copolymer with a density ≥850 kg/m3 and <905 kg/m3 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 may for example be added in quantities ≤0.050 wt. % compared to the total weight of the polyethylene material, wherein further the melt processing is performed in a melt processing unit, wherein the free radical initiator composition is dosed to the melt processing unit in a stage where the polyethylene material is in a molten condition and melt processing is conducted at a temperature of ≥160° C. and ≤240° C.
