Process for manufacturing microcapsules by interfacial polycondensation with polyoxyalkyleneamine and acid chlorides

Procédé de fabrication de microcapsules par polycondensation interfaciale avec de la polyoxyalkyleneamine et des chlorures d'acide

Résumé

The present invention relates to a process of obtaining microcapsules, comprising mainly the following stages: preparing a scarcely water-soluble organic phase containing a determined amount of acid chlorides, forming an emulsion of said organic phase in an aqueous phase, adding to the aqueous emulsion an amount of at least one polyoxyalkylene polyamine, reacting the monomers containing the amine and acid chloride functions so as to form a polyamide membrane around the emulsified organic phase, recovering the microcapsules obtained. The present invention also relates to a microcapsule.
