ABSTRACT:
Catalyst compositions comprising a first metallocene compound, a second metallocene compound, a third metallocene compound, a chemically-treated solid oxide, and an organoaluminum compound are provided. Methods for preparing and using the catalyst and polyolefins are also provided. The compositions and methods disclosed herein provide ethylene polymers having decreased haze while minimizing impact on other properties, such as dart impact.
