Title (EN) BRONSTED ACIDIC ALUMINOXANE COMPOSITIONS AND THEIR USE IN OLEFIN POLYMERIZATION CATALYST COMPOSITIONS
(FR) COMPOSITIONS D'ALUMINOXANE ACIDE DE BRONSTED ET LEUR UTILISATION DANS LA PREPARATION DE COMPOSITIONS CATALYTIQUES DE POLYMERISATION D'OLEFINES
Abstract: front page image
(EN)This invention provides activator compositions comprising Brønsted acidic aluminoxanes that are stabilized with inert functional groups, Lewis bases, or both. Methods to make and use such activator compositions to form metallocene-based olefin polymerization catalysts are also provided.
(FR)L'invention concerne des compositions d'activation contenant des aluminoxanes d'acide Brønsted stabilisés par des groupes fonctionnels inertes, des bases de Lewis ou les deux. Elle concerne également des méthodes servant à préparer et à utiliser ces compositions d'activation afin d'obtenir des catalyseurs de polymérisation d'oléfines à base de métallocènes.
