Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Corsair Clear #34. No significant weight loss of the test substance was observed below the melting temperature of the test substance (i.e. a relatively low vapour pressure was observed). The vapour pressure of molten test substance extrapolated to 20°C (293K) was 5.87 x 10-3 Pa = 4.40 x 10-5 mm Hg.
