Abstract

Se proporciona un procedimiento para encapsular un material parcialmente miscible en agua dentro de una capa de poliurea de poliuretano o de poliurea/poliuretano, procedimiento que comprende: (a) proporcionar una fase acuosa que contiene unt ensioactivo; (b) dispersar en la citada fase acuosa unsolvente orgánico inmiscible en agua, en el que se disuelven o dispersan el material parcialmente miscible en agua que se va a encapsular y elpoliisocianato para formar una dispersion degotas de solvente orgánico en la fase acuosa continua; (c) posteriormente, agregar a la dispersion un compuestopolifuncional que contiene grupos funcionales que se seleccionan entre el grupo formado por amina primaria, amina secundaria ygrupos hi droxi, por loque se forman cápsulas discretas compuestas por el material encapsulado dentro de una capa de poliurea o poliuretano; caracterizado porque se agregaa la dispersion una amina terciaria soluble en agua antes del agregadodel c ompuesto polifuncional. Se proporcionan asimismo microcápsulas compuestas porun material que es parcialmente miscible en agua, encapsulado dentro de una capa de poliurea, de poliuretano o de poliurea/poliuretano, en las cualeslacantidad del mate rial encapsulado es de, por lo menos, 5%; y un método para combatir un organismo plaga en la agricultura, la horticultura o lasilvicultura, método que comprende la aplicacion al organismo plaga o a su hábitat o, a uncultivo que se va a prot eger, de microcápsulas compuestas porun material parcialmente miscible en agua que interfiere con un proceso de vida esencial para la supervivencia de la plaga objetivo, estando dicho materialencapsulado dentro de una capade poliurea, de poliuretano o de poliurea/ poliuretano que también contiene una amina terciaria soluble en agua.
