Diffusion of methanol and water in polyurethane and polyurethane chemically modified by grafting different acrylic monomers was carried out. The absorption of these two molecules was found to vary with the nature and percentage grafting of the monomers. The possible use of chemically modified polyurethanes as membranes having high selectivity towards the interaction of alcohol and water is highlighted.
