- Conclusions:
- In conclusion, the vapour pressure of VOELOFA Monomer was determined in an experimental study conducted according to OECD test guideline 104. A vapour pressure of 1.83E-04 Pa at 20 °C and of 2.66E-04 Pa at 25 °C was caluclated from the regression quotation.
- Executive summary:
The vapour pressure of the test item VOELOFA Monomer was determined at six different temperatures 30, 45, 60, 75, 90 and 105 °C using the effusion method (weight loss) (OECD 104). Three experiments (75, 90 and 105 °C) could be evaluated as they showed relevant and reproducible weight losses. For these temperatures, 1/T was plotted against log P. A vapour pressure of 1.83E-04 Pa at 20 °C and of 2.66E-04 Pa at 25 °C was calculated from the regression quotation for the test item.

A graph with log P vs. 1/T was plotted. Since the values were correlated by a linear relation, the data could be fitted by linear regression.
