Metallocen-Alumoxan-Trägerkatalysator für die Herstellung von Polyethylen mit breiter monomodaler Molekulargewichtsverteilung |
摘要 |
The present invention relates to the production of high density polyethylene homopolymers or copolymers having a broad and monomodal molecular weight distribution wherein the polymerization process is conducted in the presence of supported metallocene-alumoxane catalysts wherein the metallocene is bridged, comprises at least a hydrogenated indenyl or fluorenyl and is isolated on its support under the form of all its conformers. |
