O-(carboxymethyl)cellulose (CMC). Quantitative analysis of the latter spectrum yields the composition of CMC in terms of the mole fractions of the eight component monomeric residues. The results on the monosaccharide composition for a series of samples having degrees of substitution in the range 0.55–2.17 are described well by Spurlin's statistical kinetic model for the arrangement of substituents (substitution
