The pervaporation separation of water-isopropanol mixtures was carried out using carboxymethylated poly(vinyl alcohol) (CMPVA) composite membranes. Carboxymethylated PVA (CMPVA) was synthesized by reacting PVA with various concentrations of monochloroacetic acid. Substitution efficiency of the CMPVA
## Abstract A solution technique was employed to prepare ZSM‐5 zeolite incorporated poly(vinyl alcohol) (PVA) membranes for the pervaporation separation of water–isopropanol mixtures. The membranes were characterized by Fourier transform infrared spectroscopy and differential scanning calorimeter.
