Abstract
A process for polymerizing ethylene is disclosed. The process uses a catalyst system which has a supported open architecture indenoindolyl complex. We surprisingly found that modifying the open architecture complex to incorporate a C -C hydrocarbyl amido group enables the production of polyethylene having good flow while maintaining high catalyst activity.
