The present invention concerns a process for the conversion of biomaterials into structural carbon products, particularly utilizing a hydrothermal treatment step that is carried out on a high molar mass organic starting material having a carbon content of &#x3e;40 wt % of the dry matter. The invention also concerns a structural carbon product obtained using such a process, which has well-defined physico-chemical properties, e.g. in terms of surface area, carbon content, density, size and shape.

Process for the hydrothermal treatment of high molar mass biomaterials

The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension, and drying the web in order to form paper or board. According to the invention the water content of the suspension from which the web is formed is 50% or less by weight of liquids. By means of the invention, energy consumption of paper manufacturing can be significantly reduced.

Method of manufacturing paper and products obtained by the method

The present invention concerns microcapsules comprising a capsule core and a capsule wall, the capsule wall being constructed from all based on the total weight of the monomers, a process for their production and their use in textiles, bindered building materials and heat transfer fluids.

Microcapsules

Aqueous dispersions of polymers which obtained by free radical suspension polymerization or free radical miniemulsion polymerization of ethylenically unsaturated monomers in an oil-in-water emulsion whose disperse phase comprises at least one fluorescent dye dissolved in at least one ethylenically unsaturated monomer and has an average particle diameter of at least 1 &#x3bc;m, in the presence of at least one surface-active compound and at least 0.5% by weight, based on the monomers, of at least one hydrophobic, nonpolymerizable, organic compound, of a hydrophobic polymer of at least one C2- to C&#x2dc;-olefin having a molar mass Mw of up to 10000, of a siloxane having a molar mass Mw of up to 5000 and/or polystyrene having a molar mass Mw of up to 10000, and of the powders obtainable from these polymer dispersions in each case by drying and comprising at least one fluorescent dye for marking of materials.

Aqueous dispersions of polymers which obtained by free radical suspension polymerization or free radical miniemulsion polymerization of ethylenically unsaturated monomers in an oil-in-water emulsion whose disperse phase comprises at least one fluorescent dye dissolved in at least one ethylenically unsaturated monomer and has an average particle diameter of at least 1&#x3bc;m, in the presence of at least one surface-active compound and at least 0.5% by weight, based on the monomers, of at least one hydrophobic, nonpolymerizable, organic compound, of a hydrophobic polymer of at least one C- to C-olefin having a molar mass Mof up to 10000, of a siloxane having a molar mass Mof up to 5000 and/or polystyrene having a molar mass Mof up to 10000, and of the powders obtainable from these polymer dispersions in each case by drying and comprising at least one fluorescent dye for marking of materials.

The invention relates to an aqueous dispersion comprising microcapsules, the capsule wall of which is formed from radically polymerized monomers and the capsule core of which comprises at least one oil, in which the capsule core comprises at least one lipophilic surfactant and the continuous phase of the dispersion comprises at least one agrochemical. In addition, the invention relates to a process for the preparation of an aqueous dispersion by (i) providing an aqueous dispersion comprising microcapsules, the capsule wall of which is formed from radically polymerized monomers and the capsule core of which comprises at least one oil and at least one lipophilic surfactant (microcapsule crude dispersion), and (ii) mixing with at least one agrochemical. Furthermore, the invention relates to the use of the microcapsule crude dispersion for the preparation of an aqueous dispersion, and also to a product comprising, as separate components, a microcapsule crude dispersion and at least one agrochemical for combined use in combating undesirable plant growth and/or in combating undesirable insect or acarid infestation on plants and/or in combating phytopathogenic fungi.
