摘要： Provided are a novel tetraarylborate compound, a catalyst composition including the same, and a method for preparing an ethylene homopolymer or an ethylene-α-olefin copolymer using the same. Specifically, the teraarylborate compound having excellent thermal stability, able to be completely dissolved in an aliphatic hydrocarbon-based solvent to facilitate the operation of commercial processes and effectively inducing the activation of a single active site catalyst, may be used as a catalyst activator to provide an ethylene-based copolymer selected from a high molecular weight ethylene homopolymer and ethylene-α-olefin copolymer having high catalyst activity.
