Abstract
The present invention relates to a supported hybrid catalyst system for ethylene slurry polymerization and a method for preparing ethylene polymer therewith. The supported hybrid catalyst system according to the present invention may exhibit high activity during ethylene slurry polymerization, and enables preparation of an ethylene polymer having a narrow molecular weight distribution but excellent processability.
