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
Water sorption and transport properties for a series of miscible blends of hydrophobic bisphenol A polysulfone and hydrophilic poly(vinyl pyrrolidone) are reported. Study was restricted to blends that remained homogeneous after exposure to liquid water. The solubility of water in the blend films inc
## Abstract Quaternized polysulfones were synthesized by the quaternization reaction of chloromethylated polysulfone with different tertiary amines β__N__,__N__βdimethylethylamine (DMEA) and __N__,__N__βdimethyloctylamine (DMOA), respectively. New blends from these quaternized polysulfones (PSFβDME
