ABSTRACT:
A process for polymerizing ethylene is disclosed. The process comprises polymerizing ethylene in a slurry reaction in the presence of a catalyst system which comprises an activator and an indenoindolyl transition metal complex on a support material. The catalyst system is slurried with an inert solvent prior to addition to the reactor. The process provides polyethylene with good bulk density.
