Abstract

DSC analysis of wax/polymer blends is carried out between 270 and 420 K. Calibration for melting point and enthalpy is normally carried out using indium (melting point 430 K), which is unsatisfactory for these materials. IUPAC organic standards covering this range tend to sublime and their onset temperatures are variable. Pure alkanes have similar thermal characteristics to wax/polymer blends and some have been well characterised by adiabatic calorimetry. They are being investigated as alternative secondary calibration standards to give more accurate thermal characterisation of wax/polymer blends. Also,n-triacontane can be used to check DSC resolution.

Zusammenfassung

Mittels DSC wurden Wachs/Polymer-Mischungen im Temperaturbereich von 270 und 420 K untersucht. Die Kalibrierung für Schmelzpunkt und-enthalpie wurde normal unter Verwendung von Indium (Schmelzpunkt 430 K) durchgeführt, was für diese Materialien unzureichend ist. Organische IUPAC-Standards, die diesen Bereich abdecken, neigen zu Sublimation und deren Einsatztemperaturen sind variabel. Reine Alkane haben ähnliche thermische Merkmale wie Wachs/Polymermischungen und einige wurden mittels adiabatischer Kalorimetrie gut charakterisiert. Sie werden als alternative Sekundär-Kalibrierstandards getestet, um eine präzisere Charakterisierung von Wachs/Polymermischungen zu erhalten. Zur Überprüfung der DSC-Auflösung kann auchn-Triakontan verwendet werden.
