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.

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.
