UNCOMPOUNDED PARTICULATE METALLOCENE-PRODUCED POLYETHYLENE |
摘要 |
An uncompounded particulate metallocene-produced polyethylene can have a multimodal molecular weight distribution and particle size distribution measured by obtaining at least four fractions by sieving. A set of Mw values including an Mw value for each fraction can be obtained. A set of Mn values including an Mn value for each fraction can be obtained. A ratio between a standard deviation value of the Mw set and a mean value of the Mw set can be equal to or less than 0.15. A ratio between a standard deviation value of the Mn set and a mean value of the Mn set can be equal to or less than 0.15. The uncompounded particulate metallocene-produced polyethylene can be prepared by a process that includes polymerization in an apparatus. The apparatus can include at least three serially connected loop reactors. |
