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 Miscibility and mutual diffusion between poly(__N__‐vinylpyrrolidone) (PVP) and short‐chain poly(ethylene glycol)s (PEGs) of different molecular weight were studied by optical wedge microinterferometry (WMI). The PVP __M__~n~ varied from 1 300 to 360 000 g · mol^−1^, whereas that of PEG
The intrinsic viscosity of polystyrene-poly(ethylene oxide) (PS-PEO) and PS-poly(ethylene glycol) (PEG) blends have been measured in benzene as a function of blend composition for various molecular weights of PEO and PEG at 303.15 K. The compatibility of polymer pairs in solution were determined on
## Abstract Poly(__N__‐vinyl‐2‐pyrrolidone) (PVP) was blended with poly[styrene‐__co__‐(4‐hydroxytyrene)] (PSH) which was obtained from the random copolymer poly[styrene‐__co__‐(4‐acetoxystyrene)] (PSA). The miscibility of PVP/PSH blends in a composition 1 : 1 by weight was evaluated by differentia
