Abstract
An olefinic polymer and a method for preparing the olefinic polymer are disclosed. The olefinic polymer has excellent melt strength, and thus has excellent bubble stability during blown film molding. The olefinic polymer has (1) a density of 0.9 to 0.95 g/cm; (2) a melt index (I) of 0.1 to 5.0 g/10 min as measured with a load of 2.16 kg at 190° C.; (3) a ratio between a melt index (I) measured with a load of 21.6 kg and a melt index (I) measured with a load of 2.16 kg at 190° C. (melt flow ratio; MFR) of 20 or more; (4) a melt tension of 55 mN or more at a velocity at break of 350 mm/s; and (5) a maximum velocity at break of 550 mm/s or more.
