  • Method for preparing colloidal particles in the form of nanocapsules
    Patent number: 7348031
    Abstract: The invention relates to a process for the preparation of dispersible colloidal systems in the form of nanocapsules whose wall consists of a polymer obtained by the polycondensation of two monomers, ? and ?, and whose core consists of a substance B, characterized in that: (1) a first liquid phase is prepared which consists of a solution of monomer ? in a solvent or solvent mixture and contains one or more surfactants and the substance B in solution or suspension; (2) a second liquid phase is prepared which consists of a non-solvent or non-solvent mixture for the monomer ? and contains the monomer ? and one or more surfactants, the solvent or solvent mixture of the first phase being miscible in all proportions with the non-solvent or non-solvent mixture of the second phase; (3) the first phase is added to the second, with moderate agitation, to give a colloidal suspension of nanocapsules, agitation being maintained until the monomers ? and ? have completely polymerized; and (4) if desired, all or part of th
