Blends of poly(N-vinyl-2-pyrrolidone) (PVP) with poly(hydroxyether of phenolphthalein) (PHP) and polyacrylonitrile (PAN) were prepared by casting from a common solvent and studied by differential scanning calorimetry. It was found that PVP was miscible with PHP and all the PVP/PHP blends were homog

## Abstract Poly(__N__βvinylβ2βpyrrolidone) (PVP) was blended with poly[styreneβ__co__β(4βhydroxytyrene)] (PSH) which was obtained from the random copolymer poly[styreneβ__co__β(4βacetoxystyrene)] (PSA). The miscibility of PVP/PSH blends in a composition 1 : 1 by weight was evaluated by differentia
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
