Beschreibung
Zusammenfassung:	A system for halogenating olefinic-based elastomer, the system comprising a first extruder, a first kneader vessel downstream of said first extruder and in fluid communication with said first extruder, a second extruder downstream of said first kneader vessel and in fluid communication with said first kneader vessel, a second kneader vessel downstream of said second extruder and in fluid communication with said second extruder; and a third extruder downstream of said second kneader vessel and in fluid communication with said second kneader vessel. La présente invention concerne un système d'halogénation d'un élastomère oléfinique, le système comprenant une première extrudeuse, une première cuve de malaxage en aval de ladite première extrudeuse et en communication fluidique avec ladite première extrudeuse, une deuxième extrudeuse en aval de ladite première cuve de malaxage et en communication fluidique avec ladite première cuve de malaxage, une seconde cuve de malaxage en aval de ladite deuxième extrudeuse et en communication fluidique avec ladite deuxième extrudeuse et une troisième extrudeuse en aval de ladite seconde cuve de malaxage et en communication fluidique avec ladite seconde cuve de malaxage.
