The i.r. spectra and the melting behaviour of blends of poly(vinyl alcohol) (PVAI) and poly(acrylic acid) (PAA) have been studied as a function of blend composition. Replacement of H-bonding interactions in pure PAA and PVAI by intermolecular interactions has been proved by analysis of the OH and C-
## Abstract Mixed matrix membranes of poly(vinyl alcohol) and poly(vinyl pyrrilidone) blends were prepared by loading with phosphomolybdic acid (PMA) and their pervaporation (PV) properties were investigated for the PV separation of isopropanol. Membrane performance shown a dependence on the extent
