P a t en t a n s p r ü c h e 1. Verfahren zur Herstellung von Platten, Folien, Schläuchen oder Hohlkörpern aus Thermoplastmaterial, dadurch gekennzeichnet, daß einem Thermoplast ein chemisches Vernetzungsmittel in solcher Menge beigemischt wird, daß bei der Weiterverarbeitung in der Wärme nur eine geringe Vernetzung eintritt, die den Erweichungsbereich erweitert, so daß die Erzeugnisse bei weiterer Verarbeitung in der Wärme z. B. beim Tiefziehen, Blasen oder Pressen elastisch bleiben und nicht dunnflussig schmelzen.P a t en t a n s p r ü c h e 1. Process for the production of panels, Films, tubes or hollow bodies made of thermoplastic material, characterized in that that a chemical crosslinking agent is added to a thermoplastic in such an amount becomes that during further processing in the heat only a slight crosslinking occurs, which extends the softening range so that the products can be processed further in the heat z.
