Title (EN) CATIONIC POLYMERISATION OF 1-OLEFINS
(FR) POLYMERISATION CATIONIQUE DE 1-OLEFINES
Abstract: front page image
(EN)A process for producing polyisobutene which has at least 70% of its unsaturation in the terminal position. The process uses a complex of boron trifluoride and alcohol as catalyst and a contact time of at least 8 minutes. The feature of the process is its ability to use longer contact times than used hitherto thereby facilitating its commercial operation and improving the control of such an operation. The high terminal unsaturation improves the reactivity of the polymer.
(FR)Procédé de production de polyisobutène présentant au moins 70 % de son insaturation en position terminale. Le procédé utilise un complexe de trifluorure de bore et d'alcool comme catalyseur et a un temps de contact d'au moins 8 minutes. Ce procédé se caractérise par la possibilité d'utiliser des temps de contact plus longs que ceux utiisés jusqu'ici, facilitant ainsi son exploitation commerciale et améliorant la commande d'une telle opération. L'insaturation de la partie élevée du terminal améliore la réactivité du polymère.
