Abstract

Procedimiento para preparar un material inmiscible en agua encapsulado, dentro de envueltas separadas de poliurea sin calentamiento exterior, caracterizado porque comprende las etapas de: (a) proporcionar en una fase acuosa una solución que comprende agua, un surfactante y un coloide protector; (b) ajustar el pH de dicha fase acuosa a un valor de 2-8 aproximadamente; (c) añadir a dicha fase acuosa de pH ajustado una fase inmiscible en agua que comprende el material inmiscible en agua a encapsular, un poliisocianato orgánico y una cantidad catalítica de un catalizador de transferencia de fases de una sal cuaternaria orgánica; (d) dispersar dicha fase inmiscible en agua en la fase acuosa para establecer gotitas de la fase inmiscible en agua en dicha fase acuosa; (e) ajustar el pH de la dispersión a un valor comprendido entre 8 y 12 aproximadamente; tras lo cual se forma una envoltura capsular de poliurea separada alrededor del material inmiscible en agua.
