Abstract: The present disclosure relates to catalysts comprising two heterogeneous chromium catalysts for the polymerization of olefins are provided herein. The catalysts, as well as related compositions and methods using the same, may be used to for the production of polyolefins, including for the production of bimodal molecular weight distribution polyolefins, e.g., polyethylene and copolymers of ethylene and 1-hexene.
