Abstract: A dispersion of cellulose fibers, a method of preparing the same and uses thereof. The dispersion is produced by providing a cellulose feedstock comprising cellulose fibers; by providing a mixture of an ionic liquid and a protic antisolvent for cellulose as a dispersion medium, the ionic liquid being selected from the group of protic salts of superbases capable of dissolving cellulose; and by mixing said cellulose feedstock into said dispersion medium so as to disperse the cellulose fibers therein to form a dispersion which is stable for at least 24 hours at room temperature. The dispersion can be used as an additive of cellulose pulps for making of fibrous products.

Abstract: A method of producing a stable aqueous dispersion of a latex, solid particles and a dispersing agent, comprising contacting the latex with an anionic dispersing agent to form a modified latex, feeding the modified latex and the solid particles to a zone of high shear forces, and simultaneously subjecting essentially all of the modified latex and the solid particles fed to said zone to high shear forces to form a latex-particle slurry. By means of the invention, over 60 wt-% of the latex can be adsorbed on the solids. Latex immobilization increases the surface strength of final coating layer and allows for a decrease of latex consumption in paper and cardboard and paint applications.
