Abstract
Redispersible microfibrillated cellulose is prepared by the addition to a liquid dispersion of the microfibrillated cellulose, an additive compound capable of substantially inhibiting hydrogen bonding between the cellulose fibrils. The microfibrillated cellulose, upon drying, is characterized by having a viscosity when redispersed in water of at least 50% of the viscosity of an equivalent concentration of the original dispersion.
