Methodology:
The method described in Marvel, et al. [1]. was used. The solubility determinations were made by adding an excess of the polymer to the solvent in a glass-stoppered bottle. The stoppered bottle was placed in a rotating device in a thermostat at 30 °C for 48 h. The saturated solution was removed weighed, evaporated and the residue weighed. This method worked well in cases where the solubility was low. In other cases, a weighed amount of solvent was added to a weighed sample of polymer. The mixture was shaken and allowed to stand at 25 °C for 48 h to see whether it became homogeneous. It was impossible to make accurate measurements even by this procedure. Hence the values given in the table for these high solubilities are to be regarded as minimum values.
Sample Information:
- Source not specified; laboratory sample; redistilled and collected over a 2°C boiling range.
- Some polymers (*) obtained from Carbide and Carbon Chemicals Corp.; others from du Pont Co.; technical grade.
Measurement Errors:
Ambient temperature: ±1 K.
Mass concentration (m/v) (1): about 10% (relative error).
