Abstract
La presente invención se refiere a un procedimiento praencapsular un material objetivo en una dispersión de partículas insolubles de núcleo-cubierta dispersas en una fase continua fluída, una mezcla que comprende: i) un material objetivo; ii) un dispersante para las partículas de núcleo en la fase continua fluída; b) combinar con el material objetivo un primer compuesto reactivo, insoluble en la fase continua fluída, el primer compuesto reactivo se selecciona de uno de i) compuestos que tienen al menos dos grupos funcionales de metileno activo por molecula y ii) agentes entrelazadores activos, reactivos de metilo; y c) combinar con la fase continua fluida un segundo compuesto reactivo, soluble o dispersable en la fase continua fluída y seleccionado de uno de i) compuestos que tienen al menos dos grupos funcionales de metileno activo por moelcula y ii) agentes entrelazadores activos, reactivos de metileno; el segundo compuesto reactivo se selecciona para ser reactivo con el primer compuesto reactivo; y el primer compuesto reactivo reacciona con el segundo compuesto reactivo, para formar cubiertas encapsuladoras polimericas alrededor de los núcleos.
