Abstract A differential scanning calorimeter has been used to study the nonfreezing of water in a series of solutions of sodium carboxymethylcellulose. In particular, the effects of molecular weight, degree of substitution, and particle size have been investigated. The results show that large amounts of water are associated with all the samples of sodium carboxymethylcellulose, suggesting a multilayer arrangement of water molecules about the solute. A change in degree of substitution has some effect on the hydration, but it appears less significant than a change in molecular weight.
