Abstract

The first examples of SHOP type nickel(II) catalysts bearing new phosphine chelate ligands comprised of a coordinating sulfonate functional group have been synthesized and structurally characterized. These catalysts show high activities in the polymerization of ethylene and can even be used without phosphine scavengers. Polyethylenes with 15-25 branches per 1000 carbon atoms are produced from ethylene monomer alone.
