Applicant's summary and conclusion

Executive summary:

There was a good deal of scatter in the data, and no definitive value for the vapour pressure at 25°C could be calculated.

However, it was estimated that the vapour pressure at this temperature was around 1.12 x 10-6kPa. It should be noted that the presence of 1-3% of triphenyl phosphate, and a small quantity of residual phenol, both of which could be expected to be appreciably more volatile than the resins, which may contributed to the scatter in the data, and to the resulting estimated vapour pressure.
