Abstract

Certain nickel [II] complexes of selected orthophosphine substituted arylsulfonamides or selected phosphine containing alkylsulfonamides catalyze the polymerization of ethylene. The polymers produced may be used as lubricants or in waxes. Some of these nickel [II] complexes and the phosphine containing ligands are also novel compounds.
