Abstract
Amorphous cellulose was obtained from different types of celluloses (microcrystalline cellulose, dissolving pulp and cotton cellulose), by regeneration with ethanol from their solutions in an SO -diethylamine- 2 dimethylsulfoxide (SO -DEA-DMSO) solvent system. Different techniques, X-ray diffraction (XRD), FTIR 2 spectroscopy and differential scanning calorimetry (DSC) were used to estimate the crystallinity degree. The values obtained for amorphous celluloses were compared with those of the initial samples and correlated with their supramolecular structures. Viscosity measurements have shown that little or no depolymerization occurs during dissolution.
