(57) [Summary] [Structure] (a) Organoaluminum oxy compound, (B) Ethylene / α-olefin copolymerization produced by a catalyst containing a transition metal compound of Group IV of the periodic table containing a ligand having a cyclopentadienyl skeleton and having a density and an intrinsic viscosity within a specific range. It is produced by a catalyst containing the combined polymer [A], (a) an organoaluminum oxy compound, and (b) a transition metal compound of Group IV of the periodic table containing a ligand having a cyclopentadienyl skeleton. Ethylene-based copolymer composition consisting of ethylene / α-olefin copolymer composition consisting of ethylene / α-olefin copolymer [B] having an intrinsic viscosity in a specific range and graft-modified ethylene (co) polymer object. [Effect] It is excellent in moldability, and the obtained film is excellent in mechanical strength and transparency, and is also excellent in adhesiveness to a highly polar material. |
