## Abstract The rheology of linear and branched metallocene polyethylenes (mβPEs) was investigated. The linear metallocenes were prepared by gasβphase polymerization, while the branched PEs were commercial resins. Molecular parameters such as __M__~__w__~, branch type, and molecular weight distribu
## Abstract A GΓΆttfert Rheotens melt strength tester was used to measure the melt strength of several commercially available polypropylene (PP) samples. The melt strengths of the polymer melts investigated were relatively low, in the range 1β10βcN, and were found to be strongly dependent on the ext
Grafting of polyethylenes is an important method used in the modification of polyolefins with functional groups. Lately, the use of extruders as polymerization reactors has increased considerably. However, knowledge of the details of the reaction in the extruder is still limited. In this investigati
