Rac-and meso-bis(1-hexamethylindenyl)phenylborane zirconium dichloride, {rac-, meso-(Ph BBI*)ZrCl2} has been synthesised and fully characterised. The slurry phase ethylene polymerisation performance of rac-(Ph BBI*)ZrCl2 immobilised on a range of methylaluminoxane (MAO)-modified, solvent-dispersed, high surface area layered double hydroxides (AMO/AIM-MgxAl-CO3 LDHs) have been studied. The polymerisation activities show a strong dependence on the nature of the LDH. Rac-(Ph BBI*)ZrCl2 supported on a MAOmodified 1-hexanol dispersed [Mg0.73Al0.27(OH)2][CO3]0.135 LDH displayed a maximum ethylene polymerisation activity of 6641 kgPE molZr −1 h −1 bar −1 at 70 °C and 2 bar ethylene. Benchmarking studies reveal that some of the rac-(Ph BBI*)ZrCl2 supported catalysts outperform a range of commonly used industrial metallocene PE catalysts.
