| 20090163638 | Dispersion of deagglomerated barium sulphate in halogenated solvents, ethers or esters - The invention discloses a dispersion of deagglomerated barium sulphate having an average primary particle size of <0.5 μm and coated with a dispersant in defined organic solvents, especially halogenated solvents such as dichloromethane. The dispersant preferably has reactive groups which are able to interact with the surface of the barium sulphate; particularly preferred dispersants are those which are able to endow the barium sulphate with a hydrophilic surface and which have reactive groups for coupling to or into polymers. The dispersion lends itself very well to incorporation into polymers such as acrylates, methacrylates, or particularly into hydrophobic polymers such as polycarbonate, or precursors thereof. | 06-25-2009 |
| 20090048380 | Particles modified by copolymers of olefinically unsaturated monomers - Particles, especially nanoparticles, being coated with copolymers (A) of olefinically unsaturated monomers (a), preparable by single-stage or multistage controlled free-radical copolymerization in an aqueous medium of (a1) at least one olefinically unsaturated monomer containing at least one chelate-forming group and (a2) at least one olefinically unsaturated monomer different from olefinically unsaturated monomer (a1) and selected from the group consisting of

| 20090020042 | Use of Nanoparticles for the Preparation of Water-Based Dispersion Adhesives - The present invention relates to the use of nanoparticles for the preparation of water-based dispersion adhesives, and especially the use of finely divided barium sulfate therein. The nanoparticles can be used with or without chemical modification. Adhesives of this kind feature improved properties, examples being improved cohesion in conjunction with comparable adhesion and higher heat resistance. Preference is given to dispersion adhesives based on polyacrylate, polyurethane, and epoxy resin. | 01-22-2009 |
| 20080312362 | Method of Generating a Dispersion of Deagglomerated Barium Sulphate in Plastics or Plastics Precursors - The invention discloses a method of incorporating deagglomerated barium sulphate having an average primary particle size of less than 0.5 μm and coated with a dispersant into plastics or precursors of plastics, for example into polyols. The deagglomerated barium sulphate is dispersed in an organic solvent, the dispersion is incorporated into the plastic or the precursor of the plastic, and the solvent is evaporated off. | 12-18-2008 |
