DSC Curves of PS

Sample

Styron 683 

Conditions

Measuring cell: DSC821^e

Pan: Aluminum standard 40 µl, pierced lid

Sample preparation: Disk cut from pellet, 12 mg

DSC measurement: First heating run from 30 to 250ºC at 10 K/min, quench-cooled to room temperature the sample changer, second heating run from 30 to 250ºC at 10 K/min.

Atmosphere: Nitrogen, 50 cm³/min

Evaluation

The first run has not been evaluated because it is distorted due to the effects of thermal history. The second run shows the results and additional information given by the glass transition evaluation. 

Conclusion

The evaluation should be performed on the second heating run.
