Abstract: Processes for preparing siloxane-modified polyisocyanates, the processes comprising: providing a polyisocyanate reactant; and reacting the polyisocyanate reactant with a hydroxyl-containing siloxane having a number-average molecular weight of 200 to 3000 g/mol and an average OH functionality of greater than or equal to 1.8, and corresponding to the general formula (I): wherein X represents an aliphatic, unbranched or branched C1 to C20 radical optionally containing ether groups; R represents a hydroxyl-functional radical; R1 represents a hydrogen or an optionally heteroatom-containing C1 to C20 hydrocarbon radical; and n is 1 to 40; siloxane-modified polyisocyanates prepared thereby, and uses therefor.

Abstract: The present invention relates to nanoparticle-modified polyisocyanates which have been modified by a special siloxane unit and consequently have improved performance properties and also storage stabilities.

Abstract: The present invention relates to hybrid organic-inorganic polyisocyanates based on polyfunctional organosilanes, metal alkoxides and alkoxysilane-containing blocked polyisocyanates for the preparation of organic-inorganic coating compositions and adhesives.

Abstract: The present invention relates to hybrid organic-inorganic polyisocyanates for the preparation of organic-inorganic coating compositions and adhesives.

Abstract: A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

Abstract: The present invention relates to innovative, nanoparticle-modified polyisocyanates, a process for their preparation and to their use in coating compositions and adhesives. The process comprises the steps of 1) reacting A) polyisocyanates with B) alkoxysilanes, and subsequently 2) incorporating by dispersion inorganic particles, optionally surface modified, having an average particle size of less than 200 nm as determined by means of dynamic light scattering in dispersion, where the alkoxysilanes are according to formula (I) Q-Z-SiXaY3-a??(I) in which Q is an isocyanate-reactive group, X is a hydrolysable group, Y is identical or different alkyl groups, Z is a C1-C12 alkylene group and a is an integer from 1 to 3.

Abstract: The present invention relates to innovative nanoparticles, to a process for preparing nanoparticles by recrystallization, and to the use thereof.

Abstract: Use of silica sols containing sulfonic acid groups and/or mercapto groups as nicroparticles in paper production, in particular for paper retention.

Abstract: A thermoplastic molding composition that features improved thermal stability and a relatively low maximum rate of decomposition in the event of fire is disclosed. The composition contains an aromatic polycarbonate and/or polyester carbonate, and a modified layered compound, the modification with organic polymer by means of a solvent-free melt process. Optional additional components include an impact modifier, a thermoplastic (co)copolymer, and a phosphorus compound.

Abstract: Solvent-containing compositions based on polychloroprene, and solvent-containing zinc oxide dispersions which are stable in storage, that can be used in adhesive and sealant compositions. The compositions can be prepared by mixing the polychloroprene composition and zinc oxide dispersion and optionally adding conventional adhesive auxiliaries and/or additives and optionally adding an additional solvent.

Abstract: Use of sheet silicates containing amino groups, sulphonic acid groups and/or mercapto groups as microparticles in papermaking, in particular for paper retention and/or drainage.
