Description

Verwendung von Polyphenylenäthern zur elektrischen Isolierung Die Erfindung betrifft die Verwendung von Polyphenylenäthern der allgemeinen Formel in der R Wasserstoff, Kohlenwasserstoffreste, Kohlenwasserstoffoxyreste, Halogenkohlenwasserstoffreste oder Halogenkohlenwasserstoffoxyreste mit wenigstens 2 Kohlenstoffatomen zwischen einem Halogenatom und dem Phenolkern mit Ausnahme von Substituenten bedeutet, die ein aliphatisches tertiäres a-Kohlenstoffatom tragen, R' die gleiche Bedeutung wie R hat oder ein Halogenatom ist und n 100 bis 1500 oder mehr ist, zur elektrischen Isolierung, insbesondere als Drahtlack.Use of polyphenylene ethers for electrical insulation The invention relates to the use of polyphenylene ethers of the general formula in which R denotes hydrogen, hydrocarbon radicals, hydrocarbonoxy radicals, halohydrocarbon radicals or halohydrocarbonoxy radicals with at least 2 carbon atoms between a halogen atom and the phenol nucleus with the exception of substituents which carry an aliphatic tertiary a-carbon atom, R 'has the same meaning as R or is a halogen atom and n is 100 to 1500 or more, for electrical insulation, especially as wire enamel.

Auf Grund ihrer ausgezeichneten physikalischen, mechanischen, elektrischen, chemischen und thermischen Eigenschaften eignen sich die Polymeren hervorragend für diesen Zweck. Die höhermolekularen Produkte haben außerordentlich hohe Erweichungspunkte im Bereich von 250 bis 300"C und darüber. Je nach der Herstellungsbedingung bleiben sie bei fortgesetztem Erwärmen im Vakuum auf 2500 C entweder thermoplastisch, oder sie erhärten zu einem unschmelzbaren Zustand, in dem sie nicht mehr in den üblichen organischen Lösungsmitteln, wie Toluol, Xylol, Chloroform, Nitrobenzol usw., löslich sind, in denen sie vor der Wärmebehandlung löslich waren. Die hervorragenden elektrischen Eigenschaften machen Schichtstoffe aus diesem Material für elektrische Bauteile, wie Schlitzkeile im Anker eines Elektromotors, Unterlagen für gedruckte Stromkreise, Schalttafeln für elektrische Geräte, Radio- und Fernsehapparate, Transformatorendplatten, Abstandsteile für Transformatorspulen usw., geeignet. Diese Teile lassen sich durch bekannte Maßnahmen, wie z.B. Extrudieren, im plastischen Zustand erzeugen. Die Polyphenylenoxyde können aber auch als Lösung oder Suspension verformt werden, indem sie zunächst in einem geeigneten Lösungsmittel gelöst und nachfolgend auf die zu isolierenden Gegenstände, z. B. Drähte, aufgebracht werden und für ein Verdampfen des Lösungsmittels gesorgt wird. Due to their excellent physical, mechanical, electrical, The polymers are ideal for chemical and thermal properties for this purpose. The higher molecular weight products have extremely high softening points in the range of 250 to 300 "C and above. Remain depending on the manufacturing condition they are either thermoplastic, or with continued heating in vacuo to 2500 C they harden to an infusible state in which they are no longer in the usual organic solvents such as toluene, xylene, chloroform, nitrobenzene, etc., soluble in which they were soluble before the heat treatment. The excellent electric Properties make laminates from this material for electrical components, such as slot wedges in the armature of an electric motor, documents for printed circuits, Control panels for electrical devices, radio and television sets, transformer end plates, Spacers for transformer coils etc., suitable. These parts can be passed through known measures, such as extrusion, produce in the plastic state. The polyphenylene oxides but can also be deformed as a solution or suspension by initially dissolved in a suitable solvent and subsequently to the to be isolated Objects, e.g. B. wires, are applied and for evaporation of the solvent is taken care of.

Die Polymeren können für diesen Zweck auch mit verschiedenen Füllstoffen und Modifizierungsmitteln usw., wie z.B. Farbstoffen, Pigmenten, Stabilisatoren, Weichmachern u. dgl., gemischt werden. The polymers can also be filled with various fillers for this purpose and modifiers, etc., such as dyes, pigments, stabilizers, Plasticizers and the like.
