A method for stabilizing colloidal suspensions of nanocrystals or nanoparticles in a solvent or solid matrix is provided by coating the nanocrystals with bulky organic molecules, specifically dendrons. By coating nanocrystals with a dense organic dendron coat and further cross-linking the dendron ligands, oxidation of the nanocrystals and dissociation of the ligands are avoided. This invention allows nanocrystals to undergo rigorous purification and processing. It may regularly be applied to a v...

The present invention concerns a method of producing a composition based on a polymer crosslinked using a silane, the method comprising the following operations: a) mixing: i) a thermoplastic base polymer or a mixture of thermoplastic base polymers containing a flame retarding filler; ii) a carrier polymer for a silane-based crosslinking agent, the carrier polymer being solid and selected from porous sponge type polymers, swellable polymers, and encapsulates, which carrier polymer is soluble or ...

The instant invention is directed to a method for reducing the viscosity of magnesium hydroxide filter cake paste which comprises adding an anionic polymer or copolymer to the magnesium hydroxide filter cake paste. The instant invention is also directed to a stable magnesium hydroxide dispersion comprising an anionic polymer, water and magnesium hydroxide.

It has now been discovered that a selected magnesium oxychloride can be mixed with a thermoplastic polymer sensitive to decomposition by water, such as polyamides or polyesters, or with fluoropolymers.
