Die Synthese von Kautschuk ist ein wichtiger Prozess: Hersteller von Gummiprodukten – ganz gleich ob Autoreifen oder Kondome – benötigen hochwertigen Kautschuk als Ausgangswerkstoff. Doch die Kautschukerzeugung ist teuer und verschlingt große Mengen an Energie. Forschern des Fraunhofer-Instituts für Angewandte Polymerforschung IAP in Potsdam ist es gemeinsam mit ihren Entwicklungspartnern LIST AG und Dow Olefinverbund GmbH gelungen, den Energiebedarf in einem wesentlichen Schritt der Kautschuksynthese um 76 Prozent zu senken.
