Title (EN) OLEFIN POLYMERIZATION CATALYST SYSTEMS AND METHODS FOR MAKING THE SAME
(FR) SYSTÈMES CATALYSEURS DE POLYMÉRISATION D'OLÉFINES ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) Borate activated catalyst systems and methods for making the same for gas phase or slurry phase olefin polymerization are provided. The catalyst system can include a first catalyst comprising a borate activated mono cyclopentadienyl metallocene compound and a second catalyst comprising a supported bis cyclopentadienyl metallocene complex. A supported bis cyclopentadienyl metallocene complex can be prepared to provide a preformed, supported catalyst, wherein the supported bis cyclopentadienyl metallocene complex comprises bis(1,3-methylbutyl cyclopentadienyl) zirconium dichloride. The preformed, supported catalyst can be mixed with mineral oil or hydrocarbon solvent to form a slurry. The slurry can be mixed with a borate activated mono cyclopentadienyl metallocene compound to form the borate activated catalyst system.
(FR) L'invention concerne des systèmes catalyseurs activés par un borate, destinés à une polymérisation d'oléfines en phase gazeuse ou en suspension, ainsi que leurs procédés de fabrication. Le système catalyseur peut comprendre un premier catalyseur comportant un composé mono cyclopentadiényl métallocène activé par un borate et un deuxième catalyseur comportant un complexe bis cyclopentadiényl métallocène supporté. Un complexe bis cyclopentadiényl métallocène supporté peut être préparé dans le but de fournir un catalyseur supporté préformé, le complexe bis cyclopentadiényl métallocène supporté comportant du dichlorure de bis(1,3-méthylbutyl cyclopentadiényl) zirconium. Le catalyseur supporté préformé peut être mélangé à une huile minérale ou à un solvant hydrocarboné pour former une suspension. La suspension peut être mélangée à un composé mono cyclopentadiényl métallocène activé, dans le but de former le système catalyseur activé par un borate.
