Title
(EN) SUPPORTED IONIC METALLOCENE CATALYSTS FOR OLEFIN POLYMERIZATION
(FR) CATALYSEURS EN ALLIAGE ORGANOMETALLIQUE IONIQUE SUPPORTES DE POLYMERISATION D'OLEFINES
Abstract
(EN)
A supported catalyst for olefin polymerization comprising a Group IV-B metallocene component and an ionic activator component comprising a cation capable of donating a proton and a labile bulky anion having a plurality of lipophilic radicals so that the anion is sterically hindered from covalently bonding with a cation produced from the Group IV-B metal of the metallocene.
(FR)
Catalyseur supporté de polymérisation d'oléfines, comprenant un composant d'alliage organométallique du groupe IV-B ainsi qu'un composant d'activation ionique comprenant un cation capable de donner un proton, et un anion volumineux labile comportant une pluralité de radicaux lipophiles de sorte que l'anion est empêché stériquement de se lier de manière covalente à un cation produit par le métal du groupe IV-B de l'alliage organométallique.
