Summary

The basic assumptions ofLodge's rubberlike-liquid constitutive equation for polymer melts and concentrated solutions are summarized. By two additional assumptions — (i) the network disentanglement assumption and (ii) the irreversibility assumption — a modified rubberlike-liquid constitutive equation is obtained, which has been shown to be a valid description of material behaviour in shear and elongational flow. In this paper a novel test — the spikestrain test — is proposed. On the basis of this experiment the assumption of irreversible destruction of network connectivity by deformation can be examined. The significance of the spike-strain test for a larger class of constitutive equations is discussed.

Zusammenfassung

Die Grundannahmen derLodgeschen Theorie der gummiartigen Flüssigkeit werden zusammengefaßt. Zwei weitere Annahmen sind notwendig, wenn man das Scher- und Dehnverhalten von Polymerschmelzen und konzentrierten Polymerlösungen bei finiten Deformationen beschreiben will: (1) die Annahme der Zerstörung des temporären Netzwerkes polymerer Flüssigkeiten mit zunehmender Deformation und (2) die Annahme, daß diese Zerstörung ein irreversibler Vorgang ist. Hier wird ein neuer Versuch, der sogenannte „Spike-Strain-Test“, vorgeschlagen. Damit ist es möglich, die Annahme einer irreversiblen Zerstörung des temporären Netzwerkes polymerer Flüssigkeiten mit zunehmender Deformation zu überprüfen. Die Bedeutung dieses Experimentes für eine größere Klasse von rheologischen Zustandsgleichungen wird diskutiert.
