Applicant's summary and conclusion

Conclusions:
Solid acrylamide sublimes near its melting point (85°C) with a vapour pressure of 230 Pa. The vapour pressure of acrylamide solutions (50%) at 25°C is < 2.5 kPa, the partial vapour pressure of acrylamide above the solution is 2.3 Pa and the vapour concentration of acrylamide in a saturated atmosphere above an aqueous solution is approximately 0.0003% (3ppm).
