Abstract
The inverse gas chromatography method was used for the investigation of the partition and diffusion coefficients of polysulfone and polyetherimide wit h NMP, gamma -butyrolactone, DMSO, acetic acid, propionic acid, THF, and wa ter over a range of temperature from 200 to 270 degreesC. The weight-fracti on infinite-dilution activity coefficients for the solvents, the Flory-Hugg ins interaction parameters, and the solubility parameters of the polymers a re reported.
