1. An olefin polymerization method comprising the steps of contacting a polymerizable olefin with a supported catalyst composition, said supported catalyst composition comprising one or more fluorided supports, one or more metallocenes, and one or more activators selected from highly fluorinated tris-arylboranes, characterized in that the degree of fluoridation of the support allows association between the fluorided support and one or more activators such that when contacted with one or more metallocenes and α

  • -olefin monomers, the supported catalyst composition exhibits a productivity of from 919 to 6012 g polymer/g metallocene·
