Abstract
An olefin-based polymer and method of making the same is disclosed herein. In some embodiments, the olefin-based polymer has multiple crystallinity and satisfies the following: (1) two or more peaks in a temperature range of −20° C. to 120° C. when measured by cross-fractionation chromatography (CFC), and T(90)−T(50)<8.0° C., (2) a soluble fraction (SF) of 1 wt % or less at −20° C. in CFC, (3) 15° C.<elution temperature (Te)<50° C., and Te has a linear correlation with a density (d) of the polymer, and satisfies the following Equation 1, Te=1,220×d−A, wherein 1,031≤A≤1,039. The olefin-based polymer according to the present invention is an olefin-based polymer having relatively increased the ratio of high crystal regions, and exhibits excellent mechanical properties such as improved tensile strength, tear strength, and flexural modulus.
