Description

Die Erfindung betrifft leitfähige Abmischungen aus Poly­ arylensulfiden, vorzugsweise Polyphenylensulfiden (PPS) mit leitfähigem Kohlenstoff.The invention relates to conductive blends of poly arylene sulfides, preferably polyphenylene sulfides (PPS) with conductive carbon.

Nach der Lehre dieser Schriften sind Abmischungen von Polyarylensulfiden mit leitfähigem Ruß durch niedrige elektrische Widerstände ausgezeichnet.According to the teachings of these writings are blends of Polyarylene sulfides with conductive carbon black by low electrical resistances excellent.

So konnten an gespritzten Formkörpern spezifische Ober­ flächen- und Durchgangswiderstände von 103 Ohm und 102 Ohm×cm gemessen werden. Jedoch sind die so erhaltenen, verminderten elektrischen Widerstände für eine Vielzahl technischer Anwendungen nicht immer befriedigend.For example, specific surface and volume resistivities of 10 3 ohms and 10 2 ohms × cm were measured on injection-molded parts. However, the resulting reduced electrical resistances are not always satisfactory for a variety of technical applications.

Es wurde nun gefunden, daß in Abmischungen von Poly­ arylensulfiden mit elektrisch leitfähigem Kohlenstoff sehr niedrigere elektrische Widerstände erreicht werden, wenn man als Kohlenstoff eine Mischung aus leitfähigem Ruß, Graphit und/oder gegebenenfalls Kokspulver, Kohlen­ stoffaser einsetzt.It has now been found that in blends of poly arylene sulfides with electrically conductive carbon very low electrical resistances can be achieved when carbon as a mixture of conductive Carbon black, graphite and / or optionally coke powder, carbon fabric fiber inserts.
