    • The two terms correspond to two different aspects: The term singlesite catalyst implies that in contrast to heterogeneous polymerization catalysts all the metal centers in homogeneous catalysts reside in identical environments. The term double site means that polymerization catalysis requires the presence of two coordination sites on the metal.

    • We prefer the fac-fac, mer-mer, and fac-mer (mer-fac) terminology over the respective cis-R, trans, and cis - terminology, for describing the wrapping modes of linear tetradentate ligands around octahedral metal centers, since they relate to the chelating ligand and not to the remaining coordination sites, give a better notion of the symmetry of the complex, and are more informative.

    • Preliminary experiments indicated that polymerization of 1-hexene by Lig2ZrBn2 activated with either [Ph3C][B(C6F 5)4] or [PhNMe2H, B(C6F 5)4, 1.5 equiv) yielded poly(1-hexene) of similar isotacticity and molecular weights as that obtained from Lig 2ZrBn2/B(C6F5)3. Polymerization of 1-hexene by Lig2ZrBn2 activated with MAO (500 equiv) led to poly(1- hexene) of slightly reduced isotacticity and considerably reduced molecular weight
