Abstract
The present invention relates to an olefin-based polymer, particularly, to a low-density olefin-based polymer introducing a highly crystalline region and showing high mechanical rigidity.
Claims13
An olefin-based polymer satisfying the following conditions (1) to (4):
- (1) a melt index (190° C., 2.16 kg load conditions) is from 0.1 to 10.0 g/10 min,
- (2) a density is from 0.875 to 0.895 g/cc,
- (3) an elution temperature (Te) measured by cross-fractionation chromatography (CFC) is from 30 to 40° C., and
- (4) 8.0≤P (75)−P (50)≤12.0 is satisfied when measuring CFC,
- wherein P (75) and P (50) are an elution amount (wt %) in a temperature range of −20 to 75° C., and an elution amount (wt %) in a temperature range of −20 to 50° C., respectively, on a temperature-elution amount graph measured by CFC.
