<p>A polymerization catalyst and a method of polymerizing ethylene, other olefins, and alkynes with such catalyst are provided by the present invention. In particular, the polymerization catalyst comprises an active cationic portion of the formula LM-R<+> wherein M is a Group VIII metal, L is a ligand or ligands which stabilize the Group VIII metal, and R is H, a hydrocarbyl radical or a substituted hydrocarbyl radical; and a stabilizing anionic portion of the formula <CHEM> wherein X is F, Cl, a hydrocarbyl radical, a substituted hydrocarbyl radical, or combinations thereof, and n is an integer from 1 to 5. Polymerization is accomplished by contacting a monomer of ethylene, other olefin or alkyne with the catalyst.</p> |
