Results and discussion
Vapour pressure
- Temp.:
- 25 °C
- Vapour pressure:
- < 1 Pa
- Remarks on result:
- other: estimated from the products free monomers by a wide safety margin
Any other information on results incl. tables
The substance consists of several components.Capa® 3050 is produced from reaction of TMP and Capa®Monomer and the reaction products are one TMP molecule + X numbers of Capa®Monomer. Capa®Monomer has a vapour pressure of 0.8 Pa and TMP 0.01. The reaction products would have a lower vapour pressure than the start material because the molecule is larger. The boiling point for Capa® 3050 is above 290 °C and for Capa®Monomer 241 °C. The higher boiling point the lower vapour pressure. The higher boiling points is confirmed at the GC determination of purity, where the difference in retention time corresponds to the size of the molecule.
Applicant's summary and conclusion
- Conclusions:
- Vapour pressure: <1 Pa at 25 ºC
- Executive summary:
Vapour pressure: <1 Pa at 25 °C
