Title (DE) HERSTELLUNG HOCHREAKTIVER POLYISOBUTENE MIT NIEDRIGEM HALOGENGEHALT
(EN) METHOD FOR PRODUCING HIGHLY REACTIVE, LOW HALOGEN POLYISOBUTENES
(FR) PRODUCTION DE POLYISOBUTENE A FAIBLE TENEUR EN HALOGENE ET HAUTEMENT REACTIF
Abstract: front page image
(DE)Beschrieben wird ein Verfahren zur Herstellung von Polyisobuten mit niedrigem Halogengehalt, bei dem man Isobuten in Gegenwart eines Katalysators polymerisiert, der eine halogenhaltige Lewis-Säure umfasst, den Katalysator abtrennt und/oder deaktiviert, und das erhaltene Polyisobuten mit einem Zeolith einer durchschnittlichen Porengröße von 5 bis 15 Å in Kontakt bringt.
(EN)The invention relates to a method for producing low halogen polyisobutenes. The inventive method is characterized in that isobutene is polymerized in the presence of a catalyst which contains a halogenated Lewis acid, the catalyst is removed and/or deactivated, and the polyisobutene so obtained is brought into contact with a zeolite having an average pore size of from 5 to 15 Å.
(FR)L'invention concerne un procédé de production de polyisobutène à faible teneur en halogène. Ce procédé consiste à polymériser l'isobutène en présence d'un catalyseur qui contient un acide Lewis halogéné ; à séparer et/ou désactiver le catalyseur et à mettre le polyisobutène obtenu en contact avec un zéolite ayant une grosseur moyenne de pores de 5 à 15 Å.
