The present invention relates to a process for the separation of at least one hydrophobic or hydrophobized material from a dispersion comprising said at least one hydrophobic or hydrophobized material and at least one second material. The process according to the present invention comprises the steps (A) to (D) which are described herein.

Ultraflotation with magnetically responsive carrier particles

The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises contacting of the mixture comprising at least one first material and at least one second material with at least one magnetic particle, or contacting of the mixture comprising at least one first material and at least one second material with at least one magnetic particle and at least one surface-modifying substance at the same time, contacting of the mixture from step (A) with at least one surface-modifying substance, if this has not been done in step (A), so that the at least one first material, the at least one surface-modifying substance and the at least one magnetic particle become attached to one another, and separation of the addition product by application of a magnetic field.

Magnetic separation of particles including one-step-conditioning of a pulp

The present invention relates to a stable mixture comprising surface-modified particles which are obtained by reacting metal oxide or semimetal oxide particles with at least one compound selected from among silicon-comprising compounds bearing one, two or three alkoxy radicals and at least one solvent, at least one surface-active substance or a mixture thereof, the use of these particles in systems in which they are brought into contact with at least one solvent, where the mass ratio of solvent to modified particle is greater than 500, and also the use of these particles in agglomeration-deagglomeration cycles.

Hydrophobic, functionalized particles

An apparatus for separating magnetic particles from a dispersion that includes magnetic particles and non-magnetic particles, the apparatus comprising; at least one arcuate canal forming 90 to 350&#xb0; of a circular arc through which the dispersion flows, at least one magnet that is movable adjacent to the canal and which forces the magnetic particles into at least one first outlet, and at least one second outlet through which the non-magnetic particles exit the canal, the apparatus further comprising treating the dispersion, or a part of the dispersion, with a hydrophilic liquid, and treating the dispersion, or a part of the dispersion, with a hydrophobic liquid.

Apparatus for resource-friendly separation of magnetic particles from non-magnetic particles

The present invention relates to a stable mixture comprising surface-modified particles which are obtained by reacting metal oxide or semimetal oxide particles with at least one compound selected from among silicon-comprising compounds bearing at least one metaloxy radical and optionally further alkoxy and/or hydroxy radical(s) and at least one solvent, at least one surface-active substance or a mixture thereof, a process for producing the mixture, the use of these particles in systems in which they are brought into contact with at least one solvent, where the mass ratio of solvent to modified particle is greater than 500, and also the use of these particles in agglomeration-deagglomeration cycles.

Transparent, tough and rigid molding compositions based on styrene-butadiene block copolymer mixtures

A block copolymer or graft copolymer with weight-average molar mass Mof at least 100 000 g/mol, comprising

Phase-separating block or graft copolymers comprising incompatible hard blocks and moulding compositions having a high stiffness

The present invention relates to thermoplastic molding compositions having a mixture of (a) from 10 to 50% by weight of a methyl methacrylate polymer as component (A), from 20 to 60% by weight of a copolymer as component (B), and from 20 to 70% by weight of a graft copolymer as component (C). Component (C) is obtainable from components (c1) a core, (c2) a first graft shell, and (c3) a second graft shell. The second graft shell (c3) is obtainable via polymerization of a C-C-alkyl ester of methacrylic acid as component (c31) and a further vinylaromatic monomer as component (c32). Graft copolymer (C) is produced via emulsion polymerization and is isolated from the reaction mixture by precipitation resulting from shear. Also disclosed are processes for producing the molding compositions, the use of the molding compositions, and moldings obtainable from the molding compositions.

The invention relates to a process for the preparation of thermoplastic molding materials comprising

Methods for producing flameproofed thermoplastic moulding compounds

The present invention relates to a thermoplastic molding composition comprising

Thermoplastic linoleum

Composition comprising at least one copolymer A composed of at least one alkylated styrene, of acrylonitrile, and, if appropriate, of at least one further monomer, at least one block copolymer B which has at least one block forming a hard phase and composed of at least one vinylaromatic monomer and has at least one block forming a soft phase and composed of at least one vinylaromatic monomer and of at least one diene, and at least one further copolymer C, and, if appropriate, one polymer D, where the copolymer C is at least one triblock copolymer composed of a first block composed of at least one vinylaromatic monomer, of a second block composed of at least one diene, and of a third block composed of at least one methyl methacrylate monomer, or comprising at least 50% by weight of methyl methacrylate, and the polymer D is at least one styrene polymer selected from glass-clear and impact-resistant polystyrene. The present invention moreover relates to a process for the preparation of the inventive compositions, to the use of the inventive compositions for the production of moldings, of foils, of fibers, or of foams, to moldings, foils, fibers, or foams comprising the inventive composition, and also to the use of the inventive composition as packaging for electronic components, such as integrated circuits (microchips) ('electronic packing'), for applications in chemical engineering, in household products, in bathroom items, e.g. toothbrush tumblers, cosmetics holders, etc., as housings, as tubes, as profiles, for medical items or medical devices, and in toys.
