Abstract

A supported catalyst system suitable for the polymerization of olefins prepared by a specific preparative route comprising optionally pretreating a support followed by addition of a neutral metal complex/activator solution. The metal complex may be a metallocene in particular a complex with trifluoromethanesulfonate ligands and the activator is a Lewis acid.
