Abstract

The composition of the Peugeot automobile bumper was studied by using DSC. The effects on the DSC curve of quenching from the melt, heating rate, cooling rate, partial scanning, and partial scanning → isothermal scanning were studied. The experimental results indicate that the sample is a blend of two polymers and it is identified as a blend of PP and HDPE by Barta's additive thermal analytical method and IR spectroscopy. A set of methods to determine the composition of polymeric materials is created by using DSC.

Zusammenfassung

Mittels DSC wurde die Zusammensetzung von Peugeout KfzStoßstangen untersucht. Der Einfluß von Abschrecken aus der Schmelze, von Aufheizgeschwindigkeit, Kühlgeschwindigkeit, partiellem Scanning und partiellem Scanning → isothermem Scanning auf den Verlauf der DSC-Kurve wurde untersucht. Die experimentellen Daten ergaben ein Gemisch aus zwei Polymeren, das mit Hilfe des additiven thermischen Analysenverfahrens nach Barta und mittels IR-Spektroskopie als ein Gemisch aus PP und HDPE identifiziert werden konnte. Eine Reihe von Verfahren zur Bestimmung der Zusammensetzung polymerer Materialien unter Anwendung von DSC wurde ausgearbeitet.
