Abstract (i) The densities of PVA film at moist states were measured at 25°C. with flotation method by using carbon tetrachloride-benzene mixtures. The density against water content curve shows a conspicuous maximum at about 1.5% water content. (ii) The water desorption expriment was carried out using the same specimen. The pore size distributions of PVA film and regenerated cellulose fibers were calculated by the Foster method from our desorption date and Hermans’ data, respectively. (iii) The results are discussed and compared with those of other investigators obtained with native and regenerated cellulose.
