Patent ID: 11629208

Abstract:
An olefin-based copolymer and a method of making the same are disclosed herein. In some embodiments, an olefin-based copolymer has a density (d) of 0.85 to 0.89 g/cc, a melt index (MI), measured at 190° C. and 2.16 kg load, of 15 g/10 min to 100 g/10 min, a number of unsaturated functional groups (total V) per 1,000 carbon atoms of 0.8 or less, a vinylene content, and a vinyl content, wherein the vinylene content, the vinyl content and the total V satisfy (a) vinylene content/total V=0.1 to 0.7 and (b) vinylene content/vinyl content=0.8 to 1.6. The olefin-based copolymer has controlled content and kind of an unsaturated functional group in the olefin-based copolymer and thus, has high flowability, and may show improved physical properties of hardness, flexural strength and tensile strength.
