Abstract:
The present invention provides organic-inorganic composite particles having an average diameter of 60 to 12'000 nm, wherein the organic-inorganic composite particles are obtainable by reacting particles A, which are particles carrying at least one functional group Ra, with particles B, which are particles carrying at least one functional group Rb, under formation of a covalent linkage between particles A and particles B. The present invention also provides compositions comprising these particles and substrates coated with these compositions.
Abstract:
The instant invention relates to shaped transition metal particles, in particular in the form of a dispersion in an aqueous and/or organic medium, the manufacture thereof and their use as an infrared (IR) absorbing agent, an IR curing agent for coatings, an additive in conductive formulations, an antimicrobial agent or for sensoring organic and/or inorganic compounds. Further, the invention relates to dispersions comprising said shaped particles and an aqueous and/or organic medium, such as a thermoplastic or crosslinkable polymer, as well as to antimicrobial compositions and products.
Abstract:
The present invention is directed to cationic nanoparticles, methods to make them, and the use of compositions containing said nanoparticles in personal care compositions or formulations. The nanoparticles are useful in personal care applications and impart antimicrobial properties to home and personal care products containing them. These cationic nanoparticles also contribute useful conditioning properties to hair-care and skin-care products.

Abstract:
The present invention relates to a composition containing modified block copolymer dispersants and dispersible inorganic or organic pigments. The block copolymers are prepared by atom transfer radical polymerisation (ATRP) and modified with a salt forming group. The pigment composition is useful for preparing coating compositions, prints, images, inks or lacquers and other disperse systems.
Abstract:
The instant invention relates to cationic alkoxyamines, which are useful as polymerization initiators/regulators in a controlled stable free radical polymerization process to produce intercalated and/or exfoliated nanoparticles from natural or synthetic clays. The invention also relates to improved nanocomposites produced by this process and to the use of these nanocomposite compositions as, for example, coatings, sealants, caulks, adhesives and as plastic additives.
