A process for forming a composition useful as a catalyst for the polymerization of addition polymerizable monomers, the steps of the process comprising: a) contacting under exchange reaction conditions a tri(hydrocarbyl)aluminum compound with a tri(fluoroaryl)boron compound; and b) contacting the reaction product from step a) without recovery or isolation thereof, with a neutral Group 3-10 metal complex.

La présente invention concerne un procédé d'élaboration de composition convenant comme catalyseur pour la polymérisation de monomères polymérisables par addition. A cet effet, on commence par a) faire réagir sur un composé tri(fluoroaryl)boré un composé à base de tri(hydrocarbyl)aluminium dans des conditions de réaction d'échange. Il ne reste plus qu'à b) prendre le produit de réaction de a) sans récupération ni isolation, et à le mettre en contact avec un complexe neutre de métaux du Groupe 3-10.
