  The present invention relates to a process for the production of modified polyethylene comprising adding a free radical initiator composition and a polar monomer in extrusion of polyethylene materials with a melt mass flow rate (MFR) as determined in accordance with ISO 1133-1 (2011) at 190° C. under a load of 2.16 kg of between 0.5 and 75 g/10 min characterized in that the free radical initiator composition is added in quantities between 0.01 wt % to 5 wt % compared to the total weight of the polyethylene material wherein the extrusion is performed at a temperature between 230° C. and 350° C. Such process allows for the production of modified polyethylenes, such as having an amount of grafted polar monomer, such as maleic anhydride, of >3 wt %, with low amount of free, unreacted monomer whilst maintaining or not significantly modifying melt properties such as melt mass flow rate.

  本发明涉及一种生产改性聚乙烯的工艺，包括在挤出聚乙烯材料时加入自由基引发剂组合物和极性单体，挤出温度为 190°C，载荷为 2.16 千克，熔体质量流动速率（MFR）根据 ISO 1133-1（2011）测定为 0.5 至 75 克/10 分钟，其特征在于自由基引发剂组合物的加入量为聚乙烯材料总重量的 0.01 重量％至 5 重量％，挤出温度为 230°C 至 350°C。这种工艺可生产改性聚乙烯，例如接枝极性单体（如马来酸酐）的含量大于 3 wt%，而游离、未反应单体的含量较低，同时保持或不显著改变熔体特性（如熔体质量流动速率）。
