Description of key information

The vapour pressure of 3-isocyanatomethyl-3,5,5-trimethylcyclo-hexylisocyanate homopolymer was determined according to OECD Guideline 104 (2006) and EU test method A.4 (2008) with the vapour pressure balance at temperatures from 180 (first quantifiable signal) to 250 °C. An Antoine equation was derived. The extrapolated value at 20 °C is 1.3E-9 Pa. Indications of decomposition at the highest temperatures were observed.
