Several binuclear vanadium complexes were synthesized and investigated as catalysts for ethylene (co)polymerization. The binuclear complexes exhibited higher activities than the mononuclear analogues in ethylene polymerization and showed moderate activity in copolymerization with polar vinyl monomers.
Several binuclear vanadium complexes were synthesized and investigated as catalysts for ethylene (co)polymerization. Under the activation of Et2AlCl, the binuclear vanadium complexes exhibited higher activities than the mononuclear analogues in ethylene polymerization. Also, the binuclear complexes showed moderate activity in the copolymerization with polar vinyl monomers such as 6-chlorohex-1-ene, 10-undecen-1-ol and methyl 10-undecenoate. In the copolymerization with methyl acrylate, the binuclear catalysts exhibited good tolerance to the polar group with activity up to 529 kg mol(V)(-1) h(-1). But only a pure polyethylene product was obtained according to the H-1 NMR spectrum.
