    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 2 ) complex. In still another embodiment, the reaction of (phenyl) (triphenylphosphine) (diphenyl-bis (trimethylsilylimino) phosphorato)-nickel with Rh(acac)(C 2 H 4 ) 2 and ethylene yield a branched polyethylene. In an alternative of this embodiment, the reaction of (phenyl) (triphenylphosphine) (methyl-bis(trimethylsilyl) amino-bis(trimethylsilylimino) phosphorato)-nickel and ethylene, with or without Ni(COD) 2 , yields a branched polyethylene.

    Abstract: Latent thermal initiators and protectant compositions that remain shelf stable at elevated temperatures, yet readily cure during a solder bump reflow process or other high temperature processing. The thermal initiators comprise thermally labile cation-anion pairs where the blocked cation prevents cure at low temperatures, and the unblocked cation initiates cure at high temperatures. Also provided is a method of making a preferred initiator comprising the cation [N-(4- methylbenzy!)-N,N-dimethylanalinium] and the anion [N(SO 2 CF 3 ) 2 ].
