Description

Lösungsmittel, Quellungsmittel und Weichmacher Gegenstand des Patents 928 793 ist die Verwendung von bestimmten hydroaromatischen Kohlenwasserstoffen als Lösungsmittel, Quellungsmittel, Verschnittmittel oder Weichmacher für Polytrifluorchloräthylen, wobei auch andere Lösungsmittel mit verwendet werden können.Solvents, swelling agents and plasticizers Subject of the patent 928 793 is the use of certain hydroaromatic hydrocarbons as a solvent, swelling agent, extender or plasticizer for polytrifluorochloroethylene, other solvents can also be used.

Es wurde nun gefunden, daß man als Quellungsmittel, Verschnittmittel und Weichmacher für Polytrifluorchloräthylen auch Cyclohexanon und dessen alkyl- und/oder chlorhaltigen Derivate sowie nichtcyclische, oberhalb 1100 siedende Ketone verwenden kann, besonders solche, die mindestens eine Alkyl-oder Arylgruppe und/oder mindestens ein Chloratom enthalten. Diese Verbindungen wirken oberhalb 1100 stark quellend und geben im Gemisch mit halogenierten Kohlenwasserstoffen klare Lösungen des genannten Polymerisates. It has now been found that swelling agents can be used as diluents and plasticizers for polytrifluorochloroethylene also cyclohexanone and its alkyl and / or chlorine-containing derivatives and non-cyclic ketones boiling above 1100 can use, especially those that contain at least one alkyl or aryl group and / or contain at least one chlorine atom. These compounds are strong above 1100 swelling and give clear solutions when mixed with halogenated hydrocarbons of the polymer mentioned.

Für die im folgenden beschriebenen Löslichkeitsversuche wurde ein Polytrifluorchloräthylen verwendet, dessen Molekulargewicht nach den von Kaufmann und Muthana, J. Polymer Science 6, S. 251 (I95I), angegebenen »NST«- und osmotischen Werten etwa 75 ooo beträgt. For the solubility tests described below, a Polytrifluorochloroethylene used, its molecular weight after that of Kaufmann and Muthana, J. Polymer Science 6, p. 251 (195I), cited "NST" and osmotic Values is about 75,000.

Beispiele sind in nachstehender Tabelle angeführt; die Lösungstemperaturen liegen meist um etwa 10 bis 20° höher als die angegebenen Entmischungstemperaturen.

Die Verbindungen der genannten Art können auch als Weichmacher verwendet werden. Zweckmäßigerweise wählt man solche Verbindungen, die einen Siedepunkt von mindestens 300° bei Normaldruck besitzen. The compounds of the type mentioned can also be used as plasticizers will. Appropriately, one chooses those compounds that have a boiling point of have at least 300 ° at normal pressure.
