Abstract

Two known imido vanadium(V) trichloride complexes, [Cl ₃V=N–C ₆H ₃-2,6-Me ₂] (1) and [Cl ₃V=N–C ₆H ₃-2,6-iPr ₂] (2), both of which have escaped testing as ethylene polymerization catalyst precursors, were synthesized and their capacity to polymerize ethylene in the presence of the co-catalyst MAO (methylaluminoxane) (Al:V ratio: 1000:1) at 10 °C is reported. The resulting polymers, from both catalysts, have molecular weights exceeding 1–2 million g/mol as suggested by the insolubility at high temperature and rheological measurements. According to the rheological and DSC annealing characterizations the synthesized Ultra-High Molecular Weight PolyEthylene from both 1 and 2 show features of a high degree of disentanglement.
