HIGH DENSITY POLYETHYLENE COMPOSITIONS WITH LONG-CHAIN BRANCHING

Provided herein are polyethylene compositions having a combination of properties including: density from about 0.930 to 0.975 g/cm3; broad molecular weight distributions (Mw/Mn≥10 and/or Mz/Mn≥80) and a highly branched architecture (e.g., g′LCB less than or equal to 0.85, preferably less than or equ...

Zusammenfassung:Provided herein are polyethylene compositions having a combination of properties including: density from about 0.930 to 0.975 g/cm3; broad molecular weight distributions (Mw/Mn≥10 and/or Mz/Mn≥80) and a highly branched architecture (e.g., g′LCB less than or equal to 0.85, preferably less than or equal to 0.75). The polyethylene compositions may further have a low molecular weight fraction (LMWF) and a high molecular weight fraction (HMWF), such that the wt % of LMWF in the compositions is greater than the wt % of HMWF. The polyethylene compositions may be suitable for making films, particularly oriented films such as uni axially (machine-direction-oriented) or biaxially-oriented films, and in particular all-PE films.
