VERFAHREN ZUR HERSTELLUNG UND ANWENDUNG EINES GETRÄGERTEN METALLOCEN-ALUMOXAN KATALYSATORS |
摘要 |
A process for the preparation of supported metallocene-alumonaxe catalysts comprising the steps of: a) reacting a metallocene with an alumoxane at a temperature comprised between 15 and 50 DEG C, b) recovering a mixture comprising an alkylmetallocenium cation and an anionic alumoxane oligomer, c) reacting said mixture with a support, and d) recovering a supported metallocene-alumoxane catalyst as a dry solid, the reaction with the support being carried out at a temperature comprised between 85 DEG C and 110 DEG C, preferably between 90 and 130 DEG C, and their use for the polymerization or copolymerization of olefins. |
