Abstract

The activation of bis(imino)pyridine cobalt-based catalysts of ethylene polymerization with methylalumoxane (MAO), AlMe₃, and AlMe₃/[CPh₃][B(C₆F₅)₄] has been studied by ¹H, ²H, and ¹⁹F NMR and EPR spectroscopy. The nature of the active sites of polymerization is discussed. The polymerization kinetics and the polymer properties for the different catalyst/activator systems were correlated with spectroscopic data.
