    摘要: The present disclosure relates to a process for continuously preparing a pelletized polyolefin composition comprising a virgin polyolefin and a recycled polyolefin. The process comprises the steps of preparing the virgin polyolefin in form of polyolefin powder or melt; providing a recycled polyolefin having a lower temperature than the virgin polyolefin of step a; transferring the virgin polyolefin, the recycled polyolefin and optionally one or more additives into a feed port of an extruder device; melting and homogenizing the virgin polyolefin, the recycled polyolefin and optionally one or more additives in the extruder device; and pelletizing the molten polyolefin composition.
