In the present invention, (1) the density (d) is 0.85 to 0.89 g / cc, and (2) the melt index (Melt Index, MI, 190 ° C., 2.16 kg load condition) is from 15 g / 10 minutes. It is 100 g / 10 minutes, (3) the number of unsaturated functional groups (total V) per 1,000 carbon atoms is 0.8 or less, and (4) carbon atoms measured via nuclear magnetic resonance spectroscopic analysis. For polymers in which vinylene, vinyl, total V per 1,000 pieces satisfy (a) vinylene / total V = 0.1 to 0.7 and (b) vinylene / vinyl = 0.8 to 1.6. The olefin-based copolymer according to the present invention exhibits improved physical properties such as hardness, bending strength, tensile strength, etc. while having high fluidity by adjusting the content and type of unsaturated functional groups in the olefin-based copolymer. obtain. |
