PROCESS FOR PREPARING POLYETHYLENE BLEND COMPRISING METALLOCENE PRODUCED RESINS AND ZIEGLER-NATTA PRODUCED RESINS |
摘要 |
A process for preparing a homogeneous polyethylene product can include producing a first polyethylene resin in the presence of a metallocene catalyst in a reactor. The first polyethylene resin can have a density of from 0.940 to 0.970 g/cm3. The first polyethylene resin can have a Low Molecular Weight (LMW) with an MI2 of between 2 and 250 g/10 min. The process can include separately producing a second polyethylene resin in the presence of a Ziegler-Natta catalyst in a reactor. The second polyethylene resin can have a High Molecular Weight (HMW) with an MI2 of between 0.01 and 15 g/10 min. The process can include physically blending together the first polyethylene resin and the second polyethylene resin to produce the homogeneous polyethylene product. |
