Olefin-based polymer and preparation method therefor

Abstract

An olefin-based polymer and a preparation method thereof are disclosed. The olefin-based polymer exhibits excellent processability and mechanical strength simultaneously. The olefin-based polymer satisfies the following Condition (1) below: 23.49 ≤ MFR 0.63 - Pc 2 ≤ 24. 7 ⁢ 6 ⁢ 2 Condition ⁢ ( 1 ) wherein in Condition (1) above, the Pc2 is the ethylene partial pressure (bar), and MFR represents Melt ⁢ flow ⁢ index ⁢ ( I 21.6 , g / 10 ⁢ min ) measured ⁢ under ⁢ a ⁢ load ⁢ of 21.6 kg ⁢ at ⁢ 190 ⁢ ° ⁢ C . Melt ⁢ flow ⁢ index ⁢ ( I 21.6 , g / 10 ⁢ min ) measured ⁢ under ⁢ a ⁢ load ⁢ of 21.6 kg ⁢ at ⁢ 190 ⁢ ° ⁢ C . of the olefin-based polymer.
