Abstract:
The present invention relates to microfibrillated cellulose (“MFC”), in particular to microfibrillated cellulose, which is morphologically different from conventional MFC known in the art and/or which provides improved water retention properties and/or improved rheological properties, in particular increased zero shear viscosity, ηo, (also known as: “viscosity at rest”, i.e. viscosity in the absence of shear forces), in solution, in particular in polyethylene glycol (PEG) as solvent, vis-a-vis conventional MFC as known in the art.

Claim (Index 14):
The process of  claim 1 , wherein the microfibrillated cellulose has a length and diameter of its cellulose fibrils and fibril bundles that are reduced vis-\u00e0-vis the respective length and diameter of the cellulose fibers and fiber bundles making up the cellulose that was used as a starting product;\n wherein at least a fraction of the fibril bundles and individual fibrils of the microfibrillated cellulose, having reduced length and diameter, has multiple bifurcations on at least one end of the main fibril into secondary fibrils, optionally bifurcations into three or more or four or five or more secondary fibrils, wherein said secondary fibrils have a smaller diameter than the non-bifurcated main fibril, wherein the ratio of the number of such bifurcated ends of fibrils/fibril bundles of the microfibrillated cellulose relative to the number of such bifurcated ends of fibrils/fibril bundles of a reference microfibrillated cellulose, and wherein the step of homogenizing the reference microfibrillated cellulose comprises passing the mechanically pretreated cellulose pulp of step (a) through a 400 \u03bcm channel and a 100 \u03bcm channel at a pressure of 2000 bar is at least 5, optionally at least 10, further optionally at least 15, wherein the number of bifurcated ends of fibrils/fibril bundles is measured by optical light microscopy at a magnification of 40 times, wherein individual fibrils or fibril bundles with a cross-sectional diameter larger than 200 nm are studied by said optical microscopy, and as measured at a solids content of 0.17% of microfibrillated cellulose in water.
