Zusatz zum Patent 742329
(Ges. v. 15. 7. 51)
Im Patent 742 329 ist ein Verfahren zur Herstellung plastischer Massen aus pulverförmiigen
Polymerisaten auf der Grundlage des Vinylchlorids beschrieben, bei dem man diese unter Vermeidung
voin (Druck und/oder Erwärmung mit einem Plastifizierungsmittel
so ischnell mischt, daß' sie gleichmäßig darin verteilt werden, bevor eine Gelatinierunig
eintritt, worauf die erhaltene Dispersion durch Erwärmen ohne Anwendung von Diruck
gelatiniert wird. Man benötigt bei diesem Verfahren keine Quellmittel oder Lösungsmittel für
die Polymerisate und keine beheizten Walzen oder Kneter, auf denen sonst meist die Gelatinierung
von Gemischen aus filmbildenden Stoffen und Weichmachern vorgenommen wird. 'Außerdem kann
man die Dispersion aus dem pulverigen Polymerisat und dem Weichmacher auf Unterlagen oder in
offene Formen bringen, dort auf die Gelatinierungstemperatur erwärmen und so unmittelbar Überzüge,
Filme und Formkörper herstellen.
Es wurde gefunden, daß man in gleicher Weise auch andere, in feinpulverige Form überführbare
thermoplastische organische Stoffe als· Polyvinylverbindungen plastisch machen und verarbeiten
kann. Stoffe dieser Art sind beispielsweise Acetyl-, Blenzyl- und Ätlhylcellulose, wie auch Chlorkautschuk.
Für die Massen eignen isioh ,alle mit ihnen
verträglichen Weichmachungs- und Plastifizierungs-
mittel, beispielsweise auch die im Hauptpatent genannten.
Die Arbeitsweise ist die gleiche, wie sie im Patent 742 329 für die Polymerisate .auf der Grundlage
des Vinylchlorids· beschrieben ist.
Die jeweils erforderlichen Gelatinierungstemperaturen lassen sich durch einen Vorversuch leicht
ermitteln. Sie sind im übrigen etwa gleich wie bei den bisher üblichen bekannten Gelatinierungs-'
mitteln für die genannten Stoffe.
E e i spiel
60 Teile feingepulverte Benzylcellulose werden in einem Intensivmischer mit 25 Teilen Trikresylphosphat,
10 Teilen Dibutylphthalat umd 5 Teilen
Benzylnaphthalin zu einer zähen Paste verrü'hrt. Diese wird, gegebenenfalls nach vorherigem
24-stündigem Stehen bei Raumtemperatur, auf 1500
ohne Anwendung von Druck erwärmt. M,an erhält dann eine homogene plastische Masse.
Man kann auch die kalte, zähe Paste in eine offene oder geschlossene Form bringen und darin
drucklos erwärmen und so beliebige Formkörper herstellen.
