Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung beladbarer Kunststoffschäume, wobei man zu wenigstens einem thermoplastischen Basispolymeren ein chemisches Treibmittel gibt, die Masse schmilzt, vor und/oder nach dem Schmelzen mischt, und die Mischung unter Bildung eines schüttfähigen, porösen Trägermaterials abkühlt, mit der Massgabe, dass man in einem Extruder oder mehrwelligen Kneter-Extruder arbeitet und wenigstens zeitweise ein inertes Gas in die Schmelze von Basispolymer und chemischem Treibmittel einleitet und wobei man das chemische Treibmittel auswählt aus der Gruppe der Diazoverbindungen, N-Nitrosoverbindungen, Sulfohydrazide, Harnstoffderivate, Guanidinderivate, Borhydrid/Wasser-Systeme, Carbonate und Hydrogencarbonate.
