Title:
ETHYLENE ALPHA-OLEFIN COPOLYMER AND RESIN COMPOSITION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/096370
Kind Code:
A1
Abstract:
An objective of the present invention is to provide an ethylene alpha-olefin copolymer containing a large amount of chains having high comonomer content and having a specific range of density and melt index. The present invention provides an ethylene alpha-olefin copolymer comprising an ethylene structural unit and an alpha-olefin structural unit, the ethylene alpha-olefin copolymer having an elution amount of 10% by weight or more at 35℃ when analyzed by means of thermal gradient interaction chromatography (TGIC).
