Zusammenfassung:	The present invention relates to water and solvent-free halogenated butyl rubber products and a process for the production thereof. The process comprises at least the steps of: a.) treating a fluid containing at least one halogenated butyl rubber and at least one volatile compound in at least one concentrator unit, b.) reheating the concentrated fluid and c.) feeding the reheated concentrated fluid into at least one extruder. Cette invention concerne des produits de type caoutchouc de butyle halogénés et un procédé pour leur production. Le procédé comprend au moins les étapes consistant à a.) traiter un fluide contenant au moins un caoutchouc de butyle halogéné et au moins un composé volatil dans au moins une unité de concentrateur, b.) re-chauffer le fluide concentré et c.) charger le fluide concentré re-chauffé dans au moins une extrudeuse.
