(57) [Summary] [Structure] The catalyst is produced by an olefin polymerization catalyst containing an organoaluminum oxy compound and at least two specific transition metal compounds, and has a density and MFR within specific ranges and a melt tension at 190 ° C. (MT) And MFR satisfy the relation shown by MT> 2.2 × MFR −0.84 , and are defined by the shear rate when the shear stress of the molten copolymer at 190 ° C. reaches 2.4 × 10 6 dyne / cm 2. Liquidity Index (FI) and MFR <150 × MFR ethylene / α that satisfies the relationship -Olefin copolymer. [Effect] It has excellent moldability, and the obtained film has excellent mechanical strength and transparency. |
