Abstract
This invention relates to new multimodal and/or broad molecular weight high density polyethylene polymers. The polymers may be made in a single reactor, preferably a gas phase reactor using a dual catalyst system comprising a pyridyldiamido transition metal compound, a metallocene compound, a support, and optionally an activator.
