Structure–property-relationship studies with ethylene polymerization catalysts of Ti, Zr and V containing heterocyclic ligands

“…1,2-Bis-benzimidazoles and 2,6-bis(benzimidazolyl)pyridine are well known compounds together with their late transition metal complexes [7][8][9][10][11][12][13][14][15][16][17]. Benzothiazole and benzoxazole contain heterocyclic sulphur and oxygen atoms and a pseudo imidazole functional group and can act as N-donor ligands with transition metals [18][19][20][21][22][23][24]. Herein we report the first zirconium, titanium and vanadium complexes of bis(benzimidazolyl, benzothiazolyl, and benzoxazolyl)methane and the importance of the CH 2 bridging unit on the performance of such catalysts in ethylene polymerization after activation with MAO.…”
