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-
By blending a rigid polymer, sodium alginate ( SA ) , and a flexible polymer, poly ( vinyl alcohol ) ( PVA ) , SA / PVA blend membranes were prepared for the pervaporation separation of ethanol -water mixtures. The rigid SA membrane showed a serious decline in flux and a increase in separation facto
## Abstract Miscibility of poly(ethyloxazoline) (PEOX) with poly(vinyl acetate) (PVAC), poly(vinyl alcohol) (PVAL) and poly(vinyl acetateβ__co__βvinyl alcohol) (ACAL copolymers) has been investigated over a wide composition range. In some blends, due to the small difference between the glass transi
