Single component, phosphine-free, initiators for ethylene homopolymerization and copolymerization with functionalized co-monomers

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