Title:
ETHYLENE-α-OLEFIN COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2011/074485
Kind Code:
A1
Abstract:
Provided is an ethylene-α-olefin copolymer that has a monomer unit based on ethylene and a monomer unit based on C3-20 α-olefin. Said ethylene-α-olefin copolymer has a melt flow rate between 0.01 and 100 g/10 min, a density between 860 and 970 kg/m³, a molecular weight distribution between 5.5 and 12, and a flow activation energy between 50 and 100 kJ/mol. Letting the maximum take-up velocity of the provided copolymer at 150°C be MTV150 and the maximum take-up velocity at 190°C be MTV190, MTV150 is at least 40 m/min and is less than MTV190.
