The biodegradability of poly(vinyl alcohol) (PVA) was investigated under different conditions by respirometric determinations, iodometric analysis, and molecular weight evaluation. Microbial inocula derived from the sewage sludge of municipal and paper mill wastewater treatment plants were used. A r

## Abstract The effect of the degree of hydrolysis of poly(vinyl alcohol) (PVA) substrates on the preparation and properties of crosslinked membranes prepared via esterification with sulfosuccinic acid (SSA) has been studied using attenuated total reflectance—Fourier transform spectroscopy (ATR–FTI
