Olefinic polymer, and method for preparing same

A method for preparing an olefinic polymer, the method comprising:

• polymerizing an olefinic monomer by a gas phase polymerization in the presence of a hybrid catalyst including:
• at least one first transition metal compound represented by the following Chemical Formula 1;
• and at least one second transition metal compound selected from a compound represented by the following Chemical Formula 2 and a compound represented by the following Chemical Formula 3, thereby obtaining an olefinic polymer, wherein the olefinic polymer has (1) a density of 0.9 to 0.95 g/cm3;
• (2) a melt index (I2.16) 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 (I21.6) measured with a load of 21.6 kg and a melt index (I2.16) 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, wherein the first transition metal compound is at least one of transition metal compounds represented by the following Chemical Formulae 1-1 and 1-2, and the second transition metal compound is a transition metal compound represented by the following Chemical Formula 2-1, and the catalyst further includes a carrier which supports the transition metal compound, and the carrier includes at least one selected from the group consisting of silica, alumina, and magnesia:
• wherein M1 and M2 are different from each other and independently of each other titanium (Ti), zirconium (Zr), or hafnium (Hf),
• X is independently of each other halogen, C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, C6-20 aryl, C1-20 alkyl C6-20 aryl, C6-20 aryl C1-20 alkyl, C1-20 alkylamido, or C6-20 arylamido, and
• R1 to R10 are independently of one another hydrogen, substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C1-20 alkyl C6-20 aryl, substituted or unsubstituted C6-20 aryl C1-20 alkyl, substituted or unsubstituted C1-20 heteroalkyl, substituted or unsubstituted C3-20 heteroaryl, substituted or unsubstituted C1-20 alkylamido, substituted or unsubstituted C6-20 arylamido, substituted or unsubstituted C1-20 alkylidene, or substituted or unsubstituted C1-20 silyl, provided that R1 to R10 may be independently of each other connected to an adjacent group to form a substituted or unsubstituted saturated or unsaturated C4-20 ring,
• wherein Me is a methyl group.
