Abstract

Un procedimiento de encapsulación de una sustancia hidrófoba líquida por policondensación interfacial, que consiste, en una primera etapa, en dispersar en una fase acuosa una fase orgánica que contiene la sustancia hidrófoba líquida a encapsular y al menos un reactivo hidrófobo polifuncional de funciones que contienen el grupo carbonilo o sulfonilo, y después, en una segunda etapa, provocar la policondensación del reactivo hidrófobo con al menos una amina polifuncional como reactivo hifrófilo
