Cellulose dissolution in an alkali based solvent: influence of additives and pretreatments [PDF]

open access: yes, 2013
The distinction between thermodynamic and kinetics in cellulose dissolution is seldom considered in the literature. Therefore, herein an attempt to discuss this topic and illustrate our hypotheses on the basis of simple experiments was made.
