| Outline of Final Research Achievements |
Boron-moiety-containing aluminoxanes were prepared from Me3Al and various arylboronic acids and compared its cocatalyst ability of olefin polymerization with methylaluminoxane (MAO), which is versatile activator of transition-metal catalysts. Incorporation of electron-withdrawing group and boron atoms to MAO greatly improved the cocatalyst ability of propylene polymerization using various group 4 metal complexes. Several spectroscopic analyses such as DOSY, 27Al, 11B NMR and IR spectroscopy revealed that the increase of cocatalyst ability is owing to the increase of Lewis acidity and bulkiness of aluminum by the incorporation of boron moieties.
