摘要： A process for preparing a polyolefin product can include providing a first high molecular weight (HMW) polyolefin resin having an HLMI of between 0.01 and 5 g/10 min, and separately providing a second low molecular weight (LMW) polyolefin resin having an MI2 of between 1 and 150 g/10 min. A device can be used to continuously physically melt and blend the first HMW polyolefin resin and the second LMW polyolefin resin to produce the polyolefin product. The device can include at least two feeding zones spatially separated and operably connected to each other. At least a art of the first HMW polyolefin resin is introduced in a first feeding zone, and at least a part of the second LMW polyolefin is introduced in a second feeding zone different from the first zone.
