Document Type and Number:
WIPO Patent Application WO/2012/115259
Kind Code:
A1
Abstract:
The present invention relates to an ethylene-α-olefin copolymer having an ethylene-based monomer unit and a monomer unit based on an α-olefin with 3 to 20 carbon atoms, wherein the density is 860 to 950 kg/m3, the melt flow rate is 0.1 to 20.0 g/10 min, the ratio of the weight-average molecular weight to the number-average molecular weight as measured by gel permeation chromatography is 2.0 to 3.5, the swell ratio is 2.0 to 2.8, and the flow activation energy is 31.0 to 35.0 kJ/mol.
