N2 - The dissolution of cellulose is a critical step for the efficient utilization of this renewable resource as a starting material for the synthesis of high value-added functional polymers. Important aspects of cellulose dissolution such as solvent-induced decrystallization and chain disentanglement are not well-understood. We have developed a phenomenological model that captures the phenomena governing the dissolution of semicrystalline polymers. This model allows the quantification of two important features, i.e., solvent effectiveness in cellulose (i) decrystallization and (ii) chain disentanglement, the balance of which controls the mechanism and kinetics of cellulose dissolution. The insights obtained from this study improve the understanding of cellulose-solvent interactions underlying decrystallization and disentanglement and their contributions in controlling the kinetics of cellulose swelling and dissolution.
