In the temperature range of 170 °C and 200 °C, weight loss was too small
for accurate measurement. A valid log p versus 1/T curve could not be
obtained for the test substance. Therefore the coefficient of
correlation (r) could not be determined. Testing at higher temperature
is not possible due to reaction and/or decomposition of the test
substance. Since accurate determination of the vapour pressure was not
possible, the weight losses were compared with the results of chrysene
at the same temperatures. The weight loss of the test substance was
lower than the weight loss of chrysene. The vapor pressure of procrylate
is therefore reported as being less than the established value for
chrysene at the relevant temperatures.
The vapor pressure of procrylat was determined by the isothermal
thermogravimetric effusion method. In the temperature range of 170 °C
and 200 °C, weight loss was too small for accurate measurement. Accurate
determination of the vapour pressure was not possible; the vapor
pressure of procrylate is therefore reported as being less than the
established value for chrysene at the relevant temperatures. The test
was done according to EU Method A.4 “Vapour pressure” and OECD 104
“Vapour Pressure Curve” and in accord with GLP guidelines but only
resulted in an upper limit; therefore this study is classified as
reliable with restriction.
