Abstract: An ethylene-based copolymer prepared using a supported hybrid metallocene catalyst is provided. The ethylene-based copolymer is prepared using a supported hybrid metallocene catalyst in which two different metallocene catalysts are supported on a support and has a bimodal or multimodal molecular weight distribution. Accordingly, the ethylene-based copolymer has superior processability, sanitation, and internal pressure creep resistance at high temperature. A supported hybrid metallocene catalyst used to prepare the ethylene-based copolymer is also provided.
