Abstract

AbstractThe sorption of polyvinyl acetate from solution in organic solvents by cellulose fibers has been investigated and found to resemble the sorption of polymers by other porous sorbents. Differences in the extents of sorption from different solvents have been attributed to competition between solvent and polymer molecules for sorption sites, and have been correlated with the Hildebrand solubility parameter. The sorption properties of cellulose fibers which had been subjected to swelling in organic liquids, to solvent‐replacement procedures, and to freeze drying were examined. The extent of sorption measures the degree of swelling and has been correlated with the properties of the swelling liquid.
