Title:
OLEFIN-BASED COPOLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/212306
Kind Code:
A1
Abstract:
The present invention relates to an olefin-based copolymer (1) having a density (d) of 0.85-0.89 g/cc, (2) having a melt index (MI) (a condition of 190°C and a load of 2.16 kg) of 15-100 g/10 min, (3) having a hardness, density and MI which meet mathematical formula 1, and (4) comprising 15-45 wt% of an α-olefin-derived repeating unit measured through nuclear magnetic resonance spectroscopy. The olefin-based copolymer according to the present invention has improved hardness, and thus can exhibit improved physical properties such as tensile strength, elongation and flexural modulus even while having high flowability.
