OLEFIN-BASED COPOLYMER, AND PREPARATION METHOD THEREFOR

Title:

OLEFIN-BASED COPOLYMER, AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/212302

Kind Code:

A1

Abstract:

The present invention relates to a 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 0.8 or less unsaturated functional groups (total V) per 1,000 carbon atoms, and (4) satisfying (a) vinylene/total V = 0.1-0.7 and (b) vinylene/vinyl = 0.8-1.6 by a vinylene, vinyl and total V per 1,000 carbon atoms, measured by nuclear magnetic resonance spectroscopy. An olefin-based copolymer according to the present invention can exhibit improved physical properties such as hardness, flexural strength and tensile strength even while having high flowability since the amount and type of unsaturated functional groups in the olefin-based copolymer are controlled.
