The boiling temperature and the respective vapour pressure was measured during this study. The individual values of the three tests and the extrapolation data are summarised in Table 1, 2 and 3 (see below). Based on the experimental results the vapour pressure curve ln Pvp versus 1/T was plotted (see Figure 1, 2 and 3 in attachment 1). The vapour pressure of 2-(2-Vinyloxyethoxy)ethyl acrylate at 25°C was extrapolated from the determined values for each test. The extrapolated vapour pressure of the first experiment was 9.09 x 10-2 hPa which is equal to 9.09 Pa at 25°C. The second test indicates a vapour pressure at 25°C of 1.45 x 10-3 hPa, which is equal to 1.45 x10-1 Pa. In the third test a vapour pressure of 3.15 x 10-2 hPa which is equal to 3.15 Pa was found. In conclusion, The vapour pressure of 2-(2-Vinyloxyethoxy)ethyl acrylate at 25°C was calculated as mean from the three experiments to be 4.13 Pa at 25°C.
