Abstract

A process for the polymerization of ethylene and/or one or more alpha-olefins comprising contacting ethylene, and/or the alpha-olefin(s) with a catalyst comprising a first component which is a bis(cyclopentadienyl) Group IVA metal compound containing a substituent capable of reacting with a cation, and a second component which is a compound having a bulky anion containing one or more boron atoms and which is substantially non-coordinating under the reaction conditions and a cation, in which process additional first component is added.
