Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 97 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- other: Tg-onset
Any other information on results incl. tables
In the 1st heat run an evaporation effect is seen between 0-150°C, probably due to rest solvent. No melting effects at temperatures between 200-250°C are visible. The solvent has disappeared in the 2nd heat run and a clear Tg of 97°C can be determined.
Applicant's summary and conclusion
- Conclusions:
- In the 1st heat run an evaporation effect is seen between 0-150°C, probably due to rest solvent. No melting effects at temperatures between 200-250°C are visible. The solvent has disappeared in the 2nd heat run and a clear Tg of 97°C can be determined.
