A high density, high polydispersity polyethylene having improved properties, and a process of producing same.

Bimodal polyethylene resins

Embodiments of the present disclosure directed towards polymerization catalysts having improved ethylene enchainment. As an example, the present disclosure provides a polymerization catalyst having improved ethylene enchainment, the polymerization catalyst comprising a zirconocene catalyst of Formula (I) where Ris a Cto Calkyl, aryl or aralkyl group, wherein Ris an Cto Calkyl, aryl or aralkyl group, and where Ris a Cto Calkyl or a hydrogen, and where each X is independently a halide, Cto Calkyl, aralkyl group or hydrogen. 

Polymerization catalysts with improved ethylene enchainment

Embodiments of the present disclosure directed towards polymerization catalysts having improved ethylene enchainment and/or improved catalyst productivity. As an example, the present disclosure provides a polymerization catalyst of Formula (I), wherein each of Rto Ris independently a Cto Calkyl, aryl or aralkyl group, or a hydrogen, wherein at least one of Rto Ris not a hydrogen, wherein M is a Group 4 metal, and wherein, each X is independently a halide, Cto Calkyl, aralkyl or hydrogen.
