Abstract
A process for modifying the paper burst strength enhancing attributes of microfibrillated cellulose may include subjecting an aqueous suspension including microfibrillated cellulose, and optionally inorganic particulate material, to high shear, wherein the high shear is generated, at least in part, by a moving shearing element, to modify the paper burst strength enhancing attributes of the microfibrillated cellulose. An aqueous suspension may include microfibrillated cellulose, and optionally inorganic particulate material, obtainable by the process. A papermaking composition and/or a paper product may be obtained from the process.
