Abstract

La présente invention concerne un procédé de préparation de microcapsules solides comprenant les étapes suivantes: a) la préparation d'une composition C1, qui est soit une composition C1a, comprenant une particule solide hydrophobe unique, soit une composition C1b comprenant plusieurs particules solides hydrophobes dispersées dans une phase hydrophile, b) l'addition sous agitation de la composition C1 dans une composition polymérique C2 à une température Tb, ce par quoi on obtient une émulsion (E1); c) l'addition sous agitation de l'émulsion (E1) dans une composition C3 à une température Tc, ce par quoi on obtient une émulsion double (E2); d) l'application d'un cisaillement à l'émulsion (E2), ce par quoi on obtient une émulsion double (E3); et e) la polymérisation de la composition C2, ce par quoi on obtient des microcapsules solides dispersées dans la composition C3.
