Abstract: The present invention relates to a method of producing holocellulose fibres by treating a wood-based raw material with an organic peroxide, wherein the method comprises charging the organic peroxide continuously to the wood-based raw material during the treatment and/or charging the organic peroxide to the wood-based raw material in at least two separate steps with an intermediate alkaline treatment step. Additionally, a process for the production of paper comprising the steps of preparing a papermaking stock comprising an aqueous pulp slurry comprising cellulosic fibres and having a fibre consistency of from 0.1 to 40% by weight, wherein the cellulosic fibres comprise or consist of holocellulose fibres, and wherein the amount of the wood-based holocellulose fibres is from 0.5 to 100% by weight, based on the total weight of the stock; providing the stock to a wire and form a web; dewatering the web; and drying the web is claimed. By the method affordable way to produce holocellulose fibres usable in the process to provide paper with high strength is provided, while effective dewatering can be obtained during the manufacturing process.

Abstract: Functionalized metal oxide particles comprising, on the surface, a radical of formula I (I) wherein the particle comprises an oxide of a metal; R1 is C, (CH2)1-12—C, or (CH2)1-12—O(O)C—C1; R2 is CR4R5, where R4 and R5 are independently selected among H and C1-C12 alkyl; and R3 is H, halo, C1-C12 alkyl, or C1-C12 haloalkyl. A process for the production of the functionalized particles; functionalized particles, obtainable by the process. A process for the production of a polymer composite comprising the functionalized particles; and a polymer composite obtainable by that process.
