The characteristic behaviour of the polysulfone (PSF), poly-(N-vinylpyrrolidone) (PVP), N-methyl-2-pyrrolidinone (NMP) ultrafiltration membrane casting solution system was investigated. Solutions containing different weight percentages of PSF and PVP were prepared. Zero-shear casting solution viscos
Membranes prepared from carboxylated polysulfone permeated benzene preferentially from benzene-cyclohexane mixtures by pervaporation. Hydrophilic polysulfones containing carboxyl groups with degrees of substitution (DS) ranging from 0.46 to 1.90 groups per repeating unit were selected for this study
