| Abstract: | A series of homogeneous titanium(IV) complexes derived from cyclohexanediol were synthesized and characterized. These catalysts, formulated as Ti–(O∩O)(OR)2], Ti–(O∩O)OPriCl] and Ti–(O∩O)2], were found to be highly active in the polymerization of ethylene at high temperature in combination with ethylaluminium sesquichloride (Et3Al2Cl3, EASC) as co‐catalyst. The resultant polyethylene had a low polydispersity index indicating the formation of single‐site catalytic species with molecular weight in the range 639–1036 g mol?1 which was analysed using 1H NMR spectroscopy and found to be linear, suggesting that a chain transfer to the aluminium of EASC occurs. © 2013 Society of Chemical Industry |
