The miscibility behaviour of blends of poly(N-vinyl pyrrolidone) (PVP) with poly(vinyl chloride) (PVC), poly(vinyl acetate) (PVAc) and vinyl chlorideΓ vinyl acetate (VCVAc) copolymer has been investigated on the basis of a viscometric approach. PVP is found to be miscible with PVC over the entire co
## Abstract Dense membranes made of poly(vinyl alcohol) (PVA) and poly(__N__βvinylβ2βpyrrolidone) (PVP) blends of different compositions were studied in gasβsweeping permeation of a waterβethanol mixture containing 10 wt.β% of water. When the PVP content increases, the steadyβstate permeation flux
