A method for continuous production of polyisobutene with a number average molecular weight MN from 500 - 50000 and a content of terminal double bonds of at least 50 mol %, comprising a single- or multi-stage polymerisation of isobutene, in the liquid phase, in the presence of a boron trifluoride catalyst and at least one oxygen containing compound, at a temperature below +40 ~C, whereby the liquid reaction phase has, at least in the first polymerisation step, a viscosity of 6 to 20 mm2 /s (measured according to DIN 51562).

La présente invention concerne un procédé permettant la préparation en continu de polyisobutène ayant un poids moléculaire moyen M¿N? compris entre 500 et 50 000 et une teneur en doubles liaisons de bout de chaîne d'au moins 50 % mol. Ce procédé comprend une ou plusieurs étapes de polymérisation continue d'isobutène en phase liquide en présence d'un catalyseur de trifluorure de bore et d'au moins un composé contenant de l'oxygène, à des températures inférieures à +40 ·C. Le procédé se caractérise en ce que la phase réactionnelle liquide a une viscosité comprise entre 6 et 20 mm?2¿/s (selon DIN 51562) au moins durant la première étape de polymérisation.
