The recent interest in high-temperature polymeric materials indicates that it would be desirable to study these materials by infrared spectroscopy at temperatures well above the 300°C upper limit of most presently-available infrared cells. A new cell has been designed and constructed which has been found useful up to 600°C, covers the infrared region from 3000 to 250 cm-1, and permits a choice of atmospheres in the cell of either air, inert gas such as nitrogen or argon, or vacuum. An additional feature is that the cell windows are easily removed for cleaning and polishing. The results obtained with this cell from room temperature to 600°C on high-temperature polymers such as poly-2,2’-(m-phenylene)-5,5’- bibenzimidazole as well as several other polymeric systems will be discussed. Recording the spectra while maintaining the desired temperature in the cell has a number of advantages over the method of external heating and cooling and then recording the spectrum.
