Abstract
The present invention generally relates to a new method of polymerizing ethylene. In one embodiment, the present invention relates to compounds utilized in the polymerization of ethylene and to a synthesis/polymerization method that uses same. In another embodiment, branched polyethylene is synthesized from an ethylene monomer using, in this embodiment, at least one nickel iminophosphonamide (PN) complex. In still another embodiment, the reaction of (phenyl)(triphenylphosphine)(diphenyl-bis(trimethylsilylimino)phosphorato)-nickel, with Rh(acac) (CH)and ethylene yield a branched polyethylene. In an alternative of this embodiment, the reaction of (phenyl)(triphenylphosphine)(methyl-cis(trimethylsilyl)amino-bis(trimethylsilylimino)phosphorato)-nickel and ethylene, with or without Ni(COD), yields a branched polyethylene.
