Abstract

METODO PARA ENCAPSULAR MATERIALES NO MISCIBLES CON AGUA EN CAPSULAS SEPARADAS DE POLIUREA SIN ADICION DE OTRO REACTANTE. COMPRENDE LA PREPARACIOM A TEMPERATURA AMBIENTE DE UNA DISPERSION CONSTITUIDA POR UNA FASE INMISCIBLE EN AGUA QUE CONTIENE EL MATERIAL NO MISCIBLE EN AGUA A ENCAPSULAR Y POLIISOCIANATOS ORGANICOS CONTENIDA EN UNA FASE ACUOSA CONSTITUIDA POR UNA DISOLUCION ACUOSA DE UN TENSOACTIVO Y UN COLOIDE PROTECTOR; Y CALENTAR LA DISPERSION A UNA TEMPERATURA COMPRENDIDA ENTRE 40JC Y 90JC DE MODO QUE SE PRODUZCA LA DISPERSION SECUENCIAL O SIMULTANEA DE CADA UNA DE LAS FASES NO MISCIBLES EN AGUA EN LA FASE ACUOSA CITADA. ESTAS MICROCAPSULAS TIENEN APLICACIONES PARA INCORPORAR HERBICIDAS.
