Title:
ETHYLENE COPOLYMER FOR BIAXIAL ORIENTATION
Document Type and Number:
WIPO Patent Application WO/2022/003499
Kind Code:
A3
Abstract:
An ethylene copolymer comprising ethylene and at least one alpha olefin having from 4 to 8 carbon atoms has a density of from 0.940 to 0.960 g/cm3, a molecular weight distribution, Mw/Mn of from 9 to 12, and a Z-average molecular weight, Mz of greater than 500,000. The ethylene copolymer is made in a multi-zone reactor system under solution phase polymerization conditions and is useful in the preparation of biaxially oriented polyethylene (BOPE) films.
