Abstract

The invention is related to a process for producing modified polyethylene having decreased melt flow rate (5 kg, 190° C.) (MFR). In particular, the present invention is directed to a process in a controlled manner for producing modified polyethylene recyclates having low MFR and low gel content directly by reactive extrusion processing.
