Abstract
La presente invención se refiere a un método para obtener microcápsulas que tienen paredes poliméricas generalmente continuas, que comprende los siguientes pasos: a) preparar una primera emulsión de materia orgánica en acuosa, que comprende una primera solución orgánica que tiene un primer material reactivo soluble en aceite disuelto en ella, y una primera solución acuosa emulsionadora, este primer material reactivo soluble en aceite siendo un poliisocianato; b) preparar una segunda emulsión de materia orgánica en acuosa, que comprende una segunda solución orgánica que tiene un segundo material reactivo, soluble en aceite, disuelto en ella y una segunda solución acuosa emulsionadora, este material reactivo, soluble en aceite, siendo una amina; y c) mezclar las emulsiones de materia orgánica en acuosa, de manera que los materiales reactivos, solubles en aceite, formen las microcápsulas, dichas microcápsulas encerrando el primer material reactivo soluble en aceite.
