摘要：

A comparative investigation into the ethene polymerisation behaviour of several mono-substituted metallocene catalysts ((CpR)(2)ZrCl2/MAO; R = H, Me, Et, Pr-i, 'Bu, SiMe3, CMe2Ph) was performed. The activity of the catalysts was found to be dependant on both steric (quantified using the Tolman cone angle, analytical solid angle and numerical solid angle measurement methods) and electronic effects (Hammett substituent parameters). The highest activity was found for the catalysts with R = Et and SiMe3. (C) 2002 Elsevier Science B.V. All rights reserved.
