| description | The present invention relates to a method for preparing an ethylene-based elastic copolymer, and more particularly, to a method for preparing an ethylene-based elastic copolymer by using a catalyst composition for preparing an ethylene-based elastic copolymer, the catalyst composition comprising a binuclear constrained geometry transition metal compound, as a main catalyst, having a structural advantage to obtain a high-molecular-weight ethylene-based elastic copolymer due to a high polymerization activity and comonomer reactivity because the binuclear constrained geometry transition metal compound has a structure in which cyclopentadiene ligands of two constrained geometry catalysts are linked by 1,4-phenylene, and one or more cocatalyst compounds selected from the group consisting of an organoaluminum compound, an organoaluminoxane compound, and a boron compound. |
