Summary

This note describes a method of preparing, from powders, specimens of intractable polymers for measurement of dynamic mechanical properties.

The powder, or a mixture of the powder and an inert filler, are compacted at room temperature in a press and if necessary sintered at an elevated temperature to achieve a low void content.

Good agreement is found between the dynamic mechanical behaviour of specimens prepared by melt and powder pressing.

Zusammenfassung

Eine Methode, aus Pulvern von schwer zu behandelnden Polymeren für die Messung der mechanischen Eigenschaften Proben zu bereiten, wird dargelegt.

Das Pulver bzw. Mischungen des Pulvers und eines inerten Füllstoffes werden bei Raumtemperatur in einer Presse komprimiert und, falls notwendig, bei höherer Temperatur gesintert, um Blasen zu vermeiden.

Es ergab sich gute Übereinstimmung zwischen den so hergestellten und anderen Proben, präpariert mit Schmelzverfahren.
