A slurry process for polymerizing ethylene is disclosed. The process comprises polymerizing ethylene in the presence of an .alpha.-olefin, hydrogen, and a catalyst comprising an activator and a supported, dimethylsilyl-bridged bis(indenoindolyl)zirconium complex. The process has high catalyst activity and produces polyethylene having a broad molecular weight distribution.
