Supramolecular structure of cellulose as a factor influencing the preparation of its ethers and esters

The change of the degree of crystallinity of mixed cellulose and the influence of this parameter on the reactivity of cellulose during preparation of soluble cellulose xanthogenate were examined based on an evaluation of the x-ray structure characteristics of samples of native cotton and regenerated cellulose. Formulas for calculating the crystallinity index of mixed celluloses and the NaOH concentration of the mercerizing solution that provided the required level of viscose filterability were proposed.
