Abstract

L'invention concerne un système d'extrusion intégré d'un polymère thermoplastique. Ce système comprend des moyens permettant de retirer directement le polymère fondu d'un réacteur de polymérisation, des moyens de transfert faisant suite aux moyens de retrait et menant à une extrudeuse munie d'une filière. Ce système permet de fabriquer des feuilles minces tubulaires sans produit intermédiaire.
