Beschreibung
Zusammenfassung:	This invention relates to composite materials and methods of their production. More especially the invention provides methods of making a composite material by paste polymerisation comprising the steps of a) forming an emulsion of at least one polymerisable monomer in an aqueous material b ) polymerising the emulsion to provide a latex comprising particles of polymer, c) adding nanoparticles to the latex said nanoparticles having at least one dimension in the range 0.5 to 200nm, and d) spray-drying the latex. L'invention concerne des matériaux composites et leur procédé de production. L'invention concerne, plus spécifiquement, des procédés de production de matériau composite par polymérisation d'une pâte, comprenant les étapes consistant : a) à former une émulsion d'au moins un monomère polymérisable dans un matériau aqueux, b ) à polymériser l'émulsion afin d'obtenir un latex comprenant des particules de polymère, c) à ajouter des nanoparticules au latex, ces dernières présentant une taille dans la plage comprise entre 0,5 et 200nm, et d) à sécher le latex par pulvérisation.
