Conclusions:
The vapour pressure of Biphenyl-2-ol, ethoxylated, esters with acrylic acid (Miramer M1142) was determined according to OECD TG 104 using the dynamic method. the vapour pressure was calculated to be 0.00027Pa @ 20oC, 0.00052 Pa @ 25oC, and 0.011 Pa @ 50oC. No reaction or decomposition was observed.
Executive summary:

The vapour pressure of Biphenyl-2-ol, ethoxylated, esters with acrylic acid (Miramer M1142) was determined according to OECD TG 104 using the dynamic method. The vapour pressure was measured in the temperature and pressure range of 202oC – 217oC and 1200 Pa – 2533 Pa, respectively. Using measured values the vapour pressure was calculated by extrapolation of the measured vapour pressure curve at three temperatures: 0.00027Pa at 20oC, 0.00052 Pa at 25oC, and 0.011 Pa at 50oC. No reaction or decomposition was observed.
