Abstract

NMR spectra of new catalyst Cp2Hf(OFl)2 (where OFl=OC10H17 is a deprotonated moiety of fenchyl alcohol, endo-1,3,3-trimethylbicyclo[2.2.1]heptan-2-ol) and its catalytic behaviour in homogeneous ethylene polymerisation activated by MAO are discussed in comparison with known (Cp2HfCl2/MAO) and previously studied (Cp2Hf(OMAd)2/MAO, where OMAd is a deprotonated moiety of 2-methyl-2adamantanol) systems. The influence of σ-bonded bridged alicyclic alcoholato-ligand on polymerisation process and final polymer properties is shown. The dependencies of the catalytic activity of these systems and those of Mw of the polyethylene obtained versus independent and dependent variables of the polymerisation process are compared and discussed.
