ABSTRACT:
Novel phosphine-free non-ionic single catalysts, and method for making such catalysts, for the homo-polymerization and copolymerization of olefins such as ethylene, α-olefins and functionalized olefins without the use of additional co-activators, are disclosed. These phosphine-free non-ionic single catalysts are also active for co-polymerization of olefins with monomers with polar functionalities. The catalyst of this invention comprise of a late transition metal with a chelating monoanionic ligand, an R group and a neutral 2 electron donor ligand. Catalysts are prepared by the oxidative addition of benzylhalide (halide=Cl, Br or I) to an appropriate metal source in the presence of a stabilizing agent, such as nitrogen based ligands, followed by the addition of the deprotonated form of the chelating ligand.
