Abstract

Procédé de préparation de particules de polymère de la dimension du micron qui consiste à préparer une solution homogène du polymère dans un matériau organique normalement liquide qui est un solvant pour le polymère, à atomiser la solution, à mettre en contact la solution atomisée avec une pellicule de liquide en déplacement qui constitue un agent non solvant pour le polymère et ensuite à récupérer dans le mélange de solvant organique et d'agent non solvant, une dispersion de particules précipitées de la dimension du micron. Application aux revêtements de surfaces métalliques.
