The character of the interaction of cellulose with water-dimethyl sulfoxide mixtures is investigated. It is shown that, in the concentration range 0 < x D < 0.28, cellulose predominantly sorbs water; in this case, in the presence of small amounts of DMSO (x D ∼ 0.1), the sorption is higher than that for pure water. It is established that the formation of hydrogen bonds between hydroxyl groups of cellulose and oxygen atoms in DMSO molecules is most probable at x D > 0.6, where large clusters dominate over hydrophobic dimers.
